As a stand alone movie. I think this movie would be great and very enjoyable. Maybe calling it something seperate like the Hobb's and Shaw spin off, so they didn't try to relate it to the rest of the franchise.
I am a huge fan of the fast and furious franchise....... but this takes the cake. They have simply jammed too many stories and too many crazy ideas into this movie.
SPOILER:
Han's return was very very anticlimactic. Simply explained as "a magic trick" from Mr. Nobody. All an illusion. Not a good enough explanation. Furthermore. Han's involvement with Mr. Nobody touches on the idea that Gisele was working for Mr. Nobody which feels very very out of place with the rest of the franchise
All in all. I do not feel this is a fast and furious movie. Rather a random action movie that doesn't feel like it was finished
