it's definitely worth seeing. after reading more online about, reading about the myth of prometheus, and thinking about certain things that were left unanswered int he movie, i've begun to like it much more. i don't think this movie will fall into the realm of sci-fi greats like the original two alien movies, but it was still pretty good. i liked how the engineers looked.
the scene where the biologist is talking to the facehugger before it fucks him up was so stupid. here's a biologist calling over an alien fucking creature, of which he has absolutely zero knowledge of. the guy that played dr. holloway was such a fucking turd and a horrible actor; the scene where noomi rapace is talking about how she's sterile was so forced and lame; charlize theron's character left something to be desired, and when you realize she's weyland's daughter was just laughable when this 90 something year old dude is about ready to crack her.
cool movie with cool visuals and a pretty cool storyline. overall, i'd recommend it, but be aware that it's not as great as you'd think it would be.
