Some of this is very accurate guys. I know no one will believe me but I have seen a cut of the movie and will tell you some things about it. I have this posted somewhere else today so I'm going to copy and paste here as well..
Okay once again I know no one is going to believe this thanks to all the idiots and trolls posting fake stuff, but I want to put this out there none the less. I was very torn on if I should say what I know or not and I thought to myself, you know what.. it's mostly already posted or we have heard about most of my spoilers already, so what the hell...
ONCE AGAIN.. HUGE SPOLIERS!! PLEASE DON'T BLAME ME FOR BEING SPOLIED!!
Okay first of all I will be back later today or tomorrow.. depending on my work schedule.. to post proof of all that I'm saying here for the doubters and none believers. If you are still with me here reading this I would like to say that this is an amazing movie! I don't think any of you can prepare yourselves for what you are going to experience June 14th guys! I have seen pretty much an entire cut of the movie in 2D and two separate scenes that were in 3D. I can't judge the 3D from what I've seen, but one of the scenes was pretty awesome so that is the one I will discuss as I don't think the other is worth mentioning.
The scene is of Zod who has taken a hostage, a mother and child, to the top of this building and he is going to execute them (in front of the world so to speak) some destruction has already taken place and cameras are rolling and watching him. He dislodges a huge tower type thing.. I don't really know what to call it? He is going to crush the woman and child with it. He shows the woman and child some amount of sympathy saying something (paraphrasing) along the lines of your sacrifice will be for the betterment of your people and i'm sure it ill be remembered by all who have witnessed it. As he throws it at them Superman swoops in like lighting catching it before it can crush them and throws it back at Zod and it lands on top of him. He turns and points to a door, I guess leading to the stairwell of the building and shouts at the woman and child to GO! They are shown running to the door and just as Superman turns around Zod is swinging this huge piece of the broken tower at him which hits him and sends him flying into another building.
Pieces of the building are falling to the ground and even the steel underneath is exposed. Superman is visibly dazed and takes a second to regain his composure. When he does he beings to grab pieces of the building and starts to fling them at Zod, who is now flywing towards Superman to finish the fight. Pieces are hitting him and he is breaking some with his fist and blocking others. The angle In which this part is shown is pretty cool in 3D as you can see like a first person perspective of superman's hands as he is throwing the pieces of the building at Zod and the camera is zooming behind the pieces as they hit him or break apart.. it is a truly breath taking action scene. The last piece is a huge steel beam from the building which hits Zod square and sends him flying through the sky, Superman shoots off like a blur to engage the battle some more I guess.. scene ends there.
Some of the things I was going to say have already been mentioned so I will not talk about that. For instance the engineered birthing and such on Krypton. The planet is destroyed in the movie! I have read some debates on that and I thought I would clear that up for every one.
I don't know the running time on the cut I was shown, but it had to be well over two hours, although it flies by! You don't look at your watch once as you are completely engaged in this movie from start to finish.
Jor-el is a bad ass in this version! Even having a fight scene or two and throwing out some pretty epic dialogue. He doesn't have as much scene time as you would think though, which Is fine by me because I have never really been a Russell Crowe fan, he does a good job in the role though.
The only part of the movie I disliked was the throw away introduction of the sequels next villain, which is done as a secret surprise, but you already see it coming an can figure it out long before the surprise revel. No I don't mean Lex, who is actually shown in the movie in a scene! Not a shadow.. they show him. I think any Superman fan can figure out who I'm referring to as I don't want to spoil everything for the none superman fans. We have been screaming for him for awhile now though! *EDIT* He has a skull ship.
There are hints at larger DC universe. Characters are mentioned and destinations, but none are shown.
I am a huge Avenges fan and a straight up Marvel guy and this destroys my precious movie

The action in this is unlike anything we have seen before in a comic movie. I was really doubting Snyder for this but I have to say he pulled it off. I have no idea what the budget for this was but it had to be massive. Every scene looks so big and the scope is amazing.. especially the scenes on Krypton and the action set pieces. The people going into this seeking some great action will be totally satisfied in every way.
Hennery Cavill is Superman! He nailed this in every way imaginable!! His presence on screen in that suit is jaw dropping! A small gripe I would have is that they barely show any Clark.. in that I mean any Daily Planet Clark. He doesn't even put the glasses on until almost the last scene of the movie. There is plenty of regular Clark though and the acting is top notch in those scenes as well.
I might forget to mention some things here so I will be back to give you some more thoughts. I'm trying to type this up at work and I'm having to stop every now and then to do things and I lose track of where I am.
Zod is really menacing in this. I guess Shannon does a good job with the dialogue but some of his facial impressions at times takes me out of the movie.. that's just my opinion though. If there is an award for screaming out dialogue, he would win it for sure! He isn't your typical bad guy in this and at the end even tries to redeem himself but it doesn't go his way. He is killed but I won't go into that any further.
Any one worried about Superman throwing a punch, don't worry! He throws many.. and some kicks, double fist action, body slamming, car and truck throwing, train smashing and pretty much anything else you can think of! Simply put, this Superman kicks ass!!!
The flying is very cool. Very different than Returns. A lot of close up flying scenes that look stunning. Its a more surreal experience. I almost want to say it looks powerful. He is fast! Always zooming around and looking awesome! The CG, especially in those scenes is really amazing. Although in one or two of the action set pieces some things looked fake, but that cant be avoided. There is a good amount of CG in this movie as well. For the practical effects fans you will be disappointed, but it looks good don't worry to much.
I will come back later but I will rank it before I leave. I would say a 9/10 for sure. This is Superman done right! As a comparison I gave avengers an 8.5/10 and TDKR a 7/10.
