This movie was horrible. It might be that I'm not a big super hero fan to begin with, or that I actually know something about science, or maybe I'm confused on what a bad screenplay is defined as. To begin with I found a lot of the dialogue very awkward and full of clichés. The line "Go get 'em tiger" should never be used unless as a joke in a movie. There were others too. Then there were some plot holes. Why would Dr. Octavius give his mechanical arms artificial intelligence, much less why did he need them in the first place? I know he needed them to set the story up but at least explain why he needs them. Second of all it really wouldn't have been too hard for the screenwriters to take 5 minutes to get a general idea of what nuclear fusion is. They were right in that fusion takes place in the sun. Thats about all they had right. Fusion is when you combine two atoms, generally hydrogen, to form larger atoms, usually helium. This releases a ton of energy. First of all fusion reactions release so much energy that they can't be used to create energy simply because they destroy everything around them. The movie has Dr. Octavius testing his new form of fusion in the middle of NYC - which would most likely destroy the entire city. The hydrogen bomb is nothing more than a fusion reaction. People are working to create "cold fusion" which would be a fusion reaction but at a temperature low enough that it won't destroy anything within a few miles of it. Then Tridium or whatever they had in the movie doesn't even exist. Much less spinning it and firing lasers at it definitely won't make if fuse together. Then at the end of the movie they solve the problem of the uncontrolled fusion reaction by putting it in the river. That is the absolute worst thing they could do. Whenever you heat water to extreme temperatues - even a fraction of the temperature of fusion - it separates into hydrogen and oxygen. You might remember the three mile island incident a while back. That was caused by water entering a nuclear reactor and creating hydrogen, which easily blows up. At the end of the movie the entire river and city should have blown up due to the massive amount hydrogen created from the fusion.
