Just watched it
It's a mixed bag with some great ideas, great practical effects, strange ADR, Pacing variations, and a stretched timeframe. Characters aren't terrible. Some do 180's for plot convenience.
It has some great body horror inspired by movies like The Thing, Society, Event Horizon, and Alien.
It's not the best nor the worst. For pacing and ADR issues, the premise and horror make up for it... though it kept going a little too long.
