.To name a few people have already mentioned:
-Goldeneye (though I loved it), Bond jumps off a cliff and falls not only faster than a plane (possible due to lift, but unlikely), but PULLS HIMSELF into said plane (the physics of that are literally impossible) and then steers the plane from crashing nose first!
-Moonraker: Bond goes to Space. 'Nuff said....actually I'll add it was lame that metal tooth guy went off a giant waterfall like he was a Looney Tunes character.
-Superman: Spins the world backwards to reverse time.
-Superman II: Kisses Lois Lane and causes her to forget the entire film!

-That despite Batman's costume being "realistic" in TDK, he still can only win fights if his enemies attack him one at a time with no sense of speed....Also how did the Joker get all those explosives wired into that hospital without anybody noticing?
-Law Abiding Citizen: (terrible movie I saw on TV last week) has Gerard Butler dig into prison for ten years into the exact cell he knew he would be placed in...apparently after he killed the
FIRST batch of innocent DA staff (nevermind a judge) nobody thought to put him under 24 hour surveillance.
-The Kids Are All Right: Mark Ruffalo sleeping with Julianne Moore. Out of character and terribly contrived.
-Ridley Scott's Robin Hood: Robin Hood's father was a renowned saxon laymen to Norman lords who inspired the philosophy behind the Magna Carta in Ridley Scott's tragically mishandled Robin Hood film. Nevermind the Magna Carta meant jack ___ for anyone who wasn't a lord in the first place. Also, Lady Marian putting on armor and fighting side by side against those dirty FRENCH.
-Inception: I loved this movie, but every time the breakneck plot would stop dead in its track during the third act (plane ride, onwards), so that Ellen Paige could ask a clunky question so that the characters could give clunky exposition to hold the audience's hand. If you're still explaining the ground rules in act 3, there might need to be some script trimming.
-The ending to The Killer Inside Me. Very...out there.
-"Bram Stoker's Dracula:" Mina choosing to drink from Dracula's chest. Still liked the movie, but Stoker's Dracula, it wasn't.
-Vertigo: Kim Novak falling out the window by accident that she had tricked Jimmy Stewart into thinking she had in the first place.
-All the comedic scenes in The Searchers. Amazing movie, but the comic relief from supporting characters would kill the atmosphere every time.
-Dial M for Murder: The police trying to intentionally discredit a conviction they already achieved in Dial M for Murder. But we wouldn't have a happy ending, otherwise.
-The CGI in both Hulk films.
-Rocky Horror Picture Show. All of it. And I wouldn't have it any other way.
