While I'm not the biggest fan of the series, I must give credit where due. The people behind the franchise have been pretty consistently besting themselves with each new entry in the series. That's not a given (just look at all those 80s horror franchises), especially when you're already 8 films in.
I will say that "besting" is pretty much limited to making the action bigger, crazier and more explosive. If you want serious character development, a solid plot or engrossing drama you better look elsewhere. If on the other hand you're content with some of the best action scenes ever put on screen, F8 has you covered.
The cast does a decent job, though mostly because their characters are tailored to their own personas. The introduction is a bit long and Theron is a disappointing villain, but once the car action begins that's all quickly forgotten. The film doesn't really slow down after that and the finale is one of the best in the series so far. Good fun.
Worthy but flawed
A mediocre attempt to revive a mediocre franchise. Hemsworth is a decent replacement, sadly Thompson falls flat besides him. The CG isn't very impressive and the creature design and voice work are dumb and childish. There's some silly action fun and the light-hearted tone keeps it watchable, but the film lacks any core qualities.
A rather plain and lazy black stoner comedy. If you think the mere idea of weed is funny, then there might be something here for you. Otherwise, it's just broad stereotypes, mediocre performances and purely functional direction. These types of comedy just aren't my thing, I like Gray better when he's doing action flicks.
