Bare in mind this is long, doesn't cover every single detail and is not exactly in a direct order.
Also, sorry if there's any spelling errors.
He comes back after a 5 year absent. He crashlands on the Kent farm, Martha finds him, no one else see's the crash...okay? For some unknown reason after he wakes up in his old bedroom, he remembers a moment from his childhood...what was the point? He finally comes face to face with his Mother who's been dying everyday from not knowing if she would ever see him again. They share a brief unemotional hug (the hug between Clark and his Mother in the first film before he left had more emotion). He goes back to work at the Daily Planet, he's only welcomed back by Jimmy, Perry White doesn't even seem to care. Clark finds out Lois has a child and has "moved on", he cracks the picture of Lois, Richard and Jason. He and Jimmy go out for a bite to eat, the plane is in trouble. Clark sits around at the bar thinking about what he should do instead of acting right away...what?! Lois is slammed around inside of the plane during the rescue, she should've died from the injuries suffered inside the plane, but instead she's able to get back to a seat and buckle herself in, she comes out of it without even the slightest bruise...what?! He's spies on Lois, Richard and Jason at home, he get's upset from what he hears and flies away...what did he expect for being gone 5 years without even saying goodbye?
We move on to Lex Luthor, who with the help of his girl Kitty, cons an old woman out of her fortune, his big plan...to create a huge piece of land made out of Kryptonite and destroy part of the United States...killing billions in the process...okay? He and his goons visit the Fortress of Solitude, where Lex get's the crystals and information he wants. Lex and his goons then walk into a museum, and under the rock collection grabs a piece of Kryptonite that's just sitting there for anyone to steal...what?! You'd think the museum owners would realize having Kryptonite just sitting around for anyone to steal would be a bad idea? Shouldn't it have been hidden in some top secret Government lab? Come on! At the same time, Kitty disracts Superman by driving through town destroying everything in her wake. Parker Posey's close up head-bobbing screaming scene got real annoying, real fast. Kitty get's upset with Lex for cutting the brakes from the car, but decides to hang around anyway...ok. Lex uses a small portion of Kryptonite to shake things up and knocks some power out.
Perry White assigns Lois and Clark to do some investigating reporting. Lois get's the Superman story, Clark get's the power outage. In the end, Lois ends up covering both stories, while Clark does nothing but stare at her with puppy dog eyes. Lois stumbles onto Lex's secret hiding place...his boat. She brings her child into harms way...smart. They're held captive. Lex tells her his entire plan...typical. Lex and his goons finally put his master plan into action by launching the Kryptonite into the water, let's not forget he has a Kryptonite shiv in his pocket which will come in handy later. Lex's Kryptonite land mass finally comes about, all it does is shake things up...where's the tsunami it should've created?!
Jason plays the piano, one of Lex's goons joins him, together they play...talk about dragging the film on. Lois sends out a distress signal via fax. She get's caught, she get's beat up, Jason throws the piano at the goon and kills him. Lois is shocked, she also suffers no physical injuries from the beating...what?! Richard and Clark get the fax thanks to Jimmy. Richard leaves to rescue Lois in his plane. Superman flies all over the city preventing disaster and death...awesome. Lex finds out his goon is dead, Lois and Jason are locked up, Jason is upset, Lois comforts him. Richard arrives on the boat after Lex and his goons leave for his new Kryptonite made land mass. Richard attempts to save Lois and Jason only to be trapped and sinks with them as the boat is broken in half by a piece of Lex's rising Kryptonite land mass.
Lois is knocked out while attempting to get out with Richard and Jason, Jason does nothing to help his Mother this time. He could've at least tried to help considering they were going to drown? They sink, Superman finally shows up to rescue them. He brings them back to the surface and back to Richards plane. Superman helps Richard's plane take off since he needs help getting it off the water. Superman goes after Lex. Somehow Superman is able to fly smoothly over a land mass made from Kryptonite and not notice the effect it has on him until after Lex punches him down...he should've crashed landed! Superman get's his ass beat. Lex takes the Kryptonite shiv out of his pocket and stabs Supes with it, and then breaks half of it off...leaving half of it still inside of Supes! Lex puts the other half back in his pocket. Superman manages to get to his feet, then plunges off of the Kryptonite land mass into the ocean below, he survives?!
Lois, Richard and Jason go back for Superman to help him after Lois suggests it. Jason spots Superman in the water. Superman sinks deep into the darkness of the ocean, he's drowning. Lois manages to swim deep into the ocean, grabs Supes and brings him to the surface...how did she hold her breath that long? Aquagirl?
They get Superman on the plane, where Lois takes out part of the Kryptonite shiv...only part of it. Superman comes to, he decides to go back and take care of business, Lois is upset by this, but he goes anyway. Superman flies up to grab some rays from the sun with Kryptonite still in him...impossible. He should be immobilized. Superman flies back down into the ocean using his heat vision to separate Lex's Kryptonite land mass from the Earth. He starts to lift it with Kryptonite still inside of him...impossible. It causes a tremor that sends Lex and his goons running for their lives, the goons die in the process. Lex and Kitty escape by helicopter, not before Kitty throws out the remaining crystals of information that Lex stole from the Fortress. The crystals land onto the Kryptonite land mass.
Superman lifts the Kryptonite land mass into outer space while more Kryptonite is seeping through the bottom, not to mention the piece still inside of him...impossible! Willpower and spirit can't overcome Kryptonite, this is not a "failure is not an option" situation...it's frickin' Kryptonite! Superman strikes a Jesus pose and falls to earth...he should've died from that. Everyone watches him fall, he's taken to the hospital, where finally the last piece of Kryptonite is removed. His survival is iffy. Richard drops Lois and Jason off at the hospital, Lois and Richard share a brief tender moment before she and Jason get out. Lois and Jason walk into the room where Superman is, she whispers to him that Jason is his son. She knows Jason is Superman's son, so she must remember sleeping with him...but she can't remember that Superman is also Clark Kent?! What?! Lois and Jason leave.
Lex and Kitty are seen stranded on a small piece of land without any fuel for their helicopter. Lex throws a fit. Superman leaves the hospital and visits his son. He gives a nice speech to Jason (who's wearing Aquaman pajamas) while he sleeps. Superman leaves and Jason notices him, causing Lois to notice him. Lois isn't shocked at all that he's up an about, she just asks if she'll see him around. Superman says he's always around...except for the 5 years that he was gone. Superman flies off into the night sky, it would've been nice if we couldl've at least seen him in this shot, too dark. We finally see him flying above the clouds as he flies away...not even bothering to concern himself with Lex Luthor's whereabouts. It's not like Lex tried to kill anyone in this movie?
If I forgot anything, sorry, typing this took forever.
Routh was given the least to work with, so I can't fairly judge him. He did alright with what he had I guess? Bosworth captured nothing of Lois Lane in her performance. Spacey was average as Lex. Langela's Perry White was boring. Huntington's Jimmy Olsen was actually pretty good. Parker Posey was more annoying than anything. There was nothing really special about this movie. It was hyped to be something spectacular, it failed at that.
Everything that's great about Superman was missing from this movie. The movie takes all logic and throws it out the window. It pretty much treats the audience like idiots. It's insulting to the audiences intelligence. The writer's obviously prove they know nothing about Superman.
In the end, this movie makes no sense. There's no follow up to anything. Bad story, no logic, hardly any action, kryptonite was misused, no need to introduce a child, bland acting, Rount given hardly any dialogue, etc.
IMO, this movie stinks. Bryan Singer and Co. dropped the ball big time. 5/10 - 2.5/5
Remember, it's just my view on SR.
