The movie franchise is in a rut. They gave the same character arc as Jason Statham for John Cena. The story was rather bland in comparison to fast 5, furious 6 and F7.
You could see the plot twist from a mile away and now the fast and furious series is more fiction than ever. No matter what you throw at the characters they still emerge unscathed. Unless they somehow found the cure for death it all seems a bit blah.
Fun to watch though... expecting more from this franchise.
