Last shot of the 'report' tanked the entire film. Obvious spoilers.
It was already is serious trouble by the end, using horror movie cliches to keep the story interesting, but the last shot of the beast was the smack in the face. Up until that final shot, the film pretended to have a brain. The point I really want to make is that the film wants so badly to be competent science fiction, but it really is just a boring horror movie.
About the beast itself-
A giant squid with lights all over it, existing in an ocean on a moon with no atmosphere, adapted to break through the ice to grab prey that had not existed before man set foot on it. I mean, surface prey COULDN'T exist, yet this thing(s) is fully capable to hunt that way, and does successfully three times out of three.
So rather than have a smart science fiction film with just the obstacles of space travel be the main problem, we get a creature feature in disguise. It can be argued that the alien was meant to inspire our imaginations about life elsewhere, and not be some movie monster antagonist, but the moment the credits roll the creepy "The Thing"-esque music starts playing. Is that really the emotion the filmmaker wants the audience to leave with? Dread? Fear of a foreign world? What a waste of a concept that could have been really moving.
