Love it!! I see most of the reviews who give this a one star rating reasons out the casting or the filming of the movie being not that great. But I think that is not the point of it, if you love scifi and the exploration of theories and ideas regarding what we do not know about time and the universe, this is for you.
It keeps you on the edge of your seat as you watch what happens to these group of friends facing a strange weird phenomena, I won't go into details about that as I'll leave it up to you. Reminding you, this is a SCI-FI thriller movie, if you are not into a movie that needs you to get your brain gears working to understand it, this is not for you. But if that's just the type you want, along with some crazy existential thriller, then I recommend this!
