I don't know, I'm really on the fence on this one. The effects look cool, but the whole premise continues to spiral further and further into silliness, at least from what I've seen.
I mean, we're not talking AVP: Requiem levels of silly or anything, just the notion that humans that have discovered vastly superior alien technology wouldn't take that immediately home to Earth to reverse-engineer is astounding to me. But, I guess we'll see what the movie yet holds.
