Don't listen to the negative reviews

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

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.

This is a small, humorous movie in some ways, but it has a huge heart. What a nice experience.
