I gave it four stars because there were parts that I simply disliked. It was pretty decent throughout, but the very end(by end I mean the last ten minutes) was such a nice twist. I liked how the movie ended, but I feel like a continuation of the ending would have been more interesting than the actual movie. The part leading up to the ending just had me like "bruh why." It had an interesting concept, though, and I probably would have given it a 3 if the last ten minutes had been different. I was scared that it wouldn't have a good ending but I kept watching anyways and I was glad that I did. I loved how the characters were developed, but I still really want a continuation of the ending...I feel that that would be really interesting to see.
