Don't Let Go Overview - Detective Jack Radcliff gets a shocking phone call from his recently murdered niece Ashley. Working together across time, they race to solve the crime before it can happen. Critic Review - Reid and Oyelowo deliver fantastic performances, but the movie's cool sci-fi premise is mostly squandered with blah visuals and an undercooked police-corruption subplot. The best part of Don't Let Go is the connection between Jack and Ashley and Jack's quickly mounting terror as he gets his strange phone call from beyond and starts scrambling to put the pieces of the puzzle together. Unfortunately, the way that puzzle comes together is far less satisfying.
