Good concept, poorly executed.

In truth, there is barely enough story here to make a film.

The plot isn't so bad, but the pace of storytelling is too slow which makes people bored. Certain moments are so obvious and unnecessary for the main plot. I would've fast-forwarded those moments if it was an online streaming. The ending looks like implying a sequel, not sure if this movie will get one

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.
