It was very authentic. A lot of suspense.

Great casting and storyline. The CGI made the IMAX experience very realistic.

Great cast! Lots of suspense. Failed to hit a climax. Then, ended with a thud!

The performances meet par but John Hawkes is the only one who delivers. The screenplay lets them down. Sure there are too many stories to tell but clumsy plants for later payoffs - no oxygen! - could come laced with more human moments/reveals that make us care more about the players. Just as troublesome is the directors lending of the pic that is alternatively too intimate and not enough.
