Dumb fun, sucks (in a good way). Kind of outdated too. It's simply not as creative as movies in this decade, but for a 2008 movie, I guess it was pretty good. A pleasant surprise, with the critters & love story, decent acting aliens. Just a little crude & for boneheads (literally) people with bones thru their noses. Those kind of pricks. I mean I don't know what else to say this movie is pretty to look at but ridiculously demented, in kind of an offensive way. A lot of crude, moronic pseudo-violent inhuman & almost pornographically gullable behavior in most of the actors. Generally an evil movie.
