Great concept but they should have consulted someone who is time travel movie buff. The recent reboot of the Twilight Zone had a similar episode which is way better. I love the fact that it showed the police brutality and how even a time traveling black teens can't escape it but I wish they had more of that in the movie. It has nonsensically time travel mechanics. They add in more power and chips needed to reroute it properly, before everytime they jumped but director forgot to do that before the last jump. As a time travel/sci-fi movie it is not even a 1/5. The themes and issues dealth here, even though it is not the best attempt I have seen, brings the movie to 2
