I was hoping that this would be another Rollng In The Deep, and for the most part it wasn't, it's sci fi about two sisters who get trrapped on either side of holes ripped in reality and the government out to weaponise some of the more weaponisable effects, as they do, but it does have one magnificently Rolling In The Deep-level burst of holyshit fuckoff horror near the end, so actually I got what I wanted out of it and am overall quite pleased.
