Whoever it is that is copying and pasting their own review on hundreds of separate accounts, is beyond sad. This is for you - simply because you can't wrap your head around a single abstract idea in this movie doesn't make it "a waste of time". What is a waste of time is copy and pasting your own opinion hundreds of times to skew the rating on google.
As for the movie - I'm not a reviewer, but I enjoyed it. Was hooked the whole time, even though the end was slightly underwhelming. You're provoked to wonder why everything is happening the way that it is, and almost expect a big reveal, which doesnt come. But in a way, I think it fit this movie, so not much of a downgrade. One thing is that it'll keep you engaged the whole time.
