The plot twist of this movie bumped it up to a soild 4 ½ stars for me. It completed something that felt like it was being lack, or at least on the surface level. The "villians" weren't really scary, or as much as the concept which was fucking brilliant. If I woke up with a evil version of myself trying to kill me, I think I would completely give up, but the action that followed the plot didn't have me feeling the pace I was hoping, but that ending, the twist within story and writing made it worth the watch. Also, lupita was a absolute doll this whole movie, this film was my first exposure to her and definitely not my last!
