Lack of good storyline.

Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

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

One of the most extraordinary films you will see this year. Take that as you want.
