The writer of this movie seems like a genius. The plot is unpredictable and the story has a steady state, what I mean is that I didn't lose interest in the middle of the movie. I've watched this many times and I still love it, it's fun! maybe for some people this movie is hard to understand but hey come on don't you guys see WHAT GENRE IS THIS?😂😂 if your brain can't get enough to catch it then don't watch it and try to watch another relaxed genre movie. I just suggest you watch movies like this or games or mysteries often because it can train your brain too! actually I think this movie is easy to digest, I like movies that need more brain thinking like this, it's great!
