Great idea and the excecution is almost perfect , I was sucked into the movie because I bought the idea until half way I just felt it lost its momentum but overall a really good sci-fi horror thriller ...the narrative was so messy and I found my self being thrown out of the movie because it was saturated with plot holes ... a movie like this should find a way to keep the audience engaged even with plot holes but this movie lost me half way and the ending just didnt live up to the promise it made from the start
