The acting was useless as expected. The poor story had its best moment in the middle. But as a sci-fi fan, I was looking forward for some nice fiction and some decent effects. But man, what on earth was this? Ok, I didn't expect much but this had the worst special effects I ever seen. The supposed CGI looked like hand-drawn animation, what a disaster! This is still 2008, so why even bother to do a sequel to a moderate sci-fi/action flick if you don't have what it takes to make it? The ending was not much to cheer for either, it was too short and felt liked they cut half an hour of it. Honestly... I almost regret I wasted my time on this... But anyway the teenaged guys gets their share of boobs and silicone lips filled to the rim.
In the beginning I did not know if I like, or dislike this movie. But eventually I realized the latter it is, I dislike the whole saga and movie. The movie felt strange in a bad, sick and weird way blended in some kind of Sci-Fi that was reminiscent of the 60's. The movie left me with feelings of ugliness and horribleness. However, I can imaging why some people are fans of the novel and the movie, it is original in its way. But I definitely think it's terrible.
Immature or no story with many plot holes, bad acting and poor direction, however some of the effects were pretty descent. But just effects with flashy lights doesn't impress me much (even if I'm a Sci-Fi freak). And by the way, the interview scenes seen in the trailer are not even in the movie, the trailer is a deception, IMHO :-/
Reminds a little of Cube but this one has a slooow paaacing stooory, no thrill, no suspense, no excitement... nothing. And it's very lame and amateurish. A total waste of time, in my opinion. - I give it 1 star for the pretty good half minute in the beginning and zero stars for the rest.
