Concept: 2/4 (Indifferent)
Story: 3/4 (Good). It's not by any means good writing, but they deserve some serious credit for making this idea work as well as they did, and for not getting too sidetracked with B movie cliches.
Characters: 0/4 (Terrible)
Dialog: 0/4 (Terrible)
Pacing: 2/4 (Indifferent)
Cinematography: 2/4 (Indifferent)
Special effects/design: 3/4 (Good)
Acting: 2/4 (Indifferent)
Music: 2/4 (Indifferent)
Subjective Rating: 6/10 (Okay, 2/4). There's a point in the movie, about halfway through, when you finally see the rocks doing their thing. Up until then, the whole movie seemed absurd and silly. But when you see it for yourself, it's convincing and logical and neatly pulls everything together. Maybe it helps that I know so little about geology that I can absorb the pseudoscience without objections, but they had me accepting this premise as entirely plausible. I think that's pretty cool.
Objective Rating (Average): 1.8/4 (Eh)
