Let's be realistic.

It's an amazing and heartbreaking story.

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 those movie experiences that is so good it makes you realize you've been grading everything else on a curve.
