Another one of my watch-the-first-part-before-watching-the-sequel efforts.
The movie - seems to be a bit of a stretch to call it a movie it's more like a comic book on celluloid. And when you have said that, you have said everything. There is no maturity in the treatment of the topic. The invasion of aliens has been done to death in many forms and if skillfully done there is potential to make about 100 more movies on this topic, good movies I mean. This one hangs together with gum and rubber bands.
The hero character is kind of weird, they want him to be an innocent guy, but he's too slick for that even though he looks like a doofus. He talks more like a used-car salesman than a teenage student. There are big gaping holes in the logic, all through the movie.
When you make a science fiction movie, you show technology that has not been invented yet. Since it's not been invented you can't explain how it works, because so far, it doesn't. Those areas are supposed to be missing in such a movie and that's understandable. But, on the whole, a broad, general understanding of the main technology is provided and everything else is kept on a consistent level with that theory. Otherwise it's just a truckload of hooey, black-magic and woodoo. Well, that's what we have here. I don't expect logic and common sense from all movies, definitely not from Bollywood movies, but in science movies I expect to see logic.
All the usual sci-fi movie stereotypes are there - the nervous genius nobody person, the omniscient hacker, the hate-able bureaucrat, the underdog our hero, the innocent unknowing parents, the government authority figures, mention of the US president, and lots of computers, all are present. And none manage to impress.
Dialog is ok in some places and completely loses touch in most places. The lines are good, and delivered well, but somehow you get the impression of having wandered on to a movie set. Until you can create that semblance of reality in the viewer's mind, you can't inspire awe at the strange and extraordinary happenings.
Being a comic book screenplay the end is not hard to guess. When you have something as powerful as a cube that creates universes as the object of hunt, you kind of guess, that it's going to be destroyed in the end. And when you learn there's sacrifice involved in destroying it, then you are 101% sure that it's going to be destroyed.
Oh, just to quote a logic flaw to show what I mean - the hero is running clutching the all powerful cube to his chest, he stumbles, falls, the cube touches the road, enormous energy flows out, through the road to other things, cell-towers shake, building sway, electronic equipment goes wild, people are shaken up. But when the guy is carrying it in his arms, with no insulation or anything, NOTHING happens to him, no positive effect, no negative effect. Just no effect. What the hell!
Considering the screenplay and direction it's overly long and tedious. The few attempts at comedy are pathetic. Romance fails to grip. Action sequences have been ruined by the technology-oriented camera work where you are not supposed to guess what the hell is going on, or who is winning. Full of sci-fi movie cliches and quite predictable flow.
Conclusion: If you are over 12, don't watch it. I had acquired both Transformers 1 and 2, but after watching 1, I am not wasting time on 2. I might re-run the Back to The Future trilogy instead!
