Good review.

I think the movie had too many supporting actors who should have been cameos. That leads to too many story arcs. It is not possible to develop and follow that many characters and story arcs in such a short period of time, so we end up not invested (i.e. caring much about the characters and story arcs. So the middle is just "meh" while we're half following these characters/story arcs.

I'd say maybe 7.0/10.
