I thought it was okay, but disappointing. The action is good, as are the three leads, but the plot is bad, even by F&F standards.
The worst part, by far, are the Leitch-enforced comedy cameos: Rob Delaney is fine, and Kevin Hart is tolerable, but Ryan Reynolds is an abomination. He's basically just playing Deadpool, and doesn't fit the tone of the film at all. It dragged the movie down an entire letter grade for me. It's truly the worst performance of the year for me.
Just as annoying is that his character is completely unnecessary. He's there to set Hobbs on the case, but Hobbs is already investigating it at the start of the movie! Similarly, there's no need for the Rob Delaney character, as Shaw's already involved because of his sister!
Also, this movie posits that Jason Staham (52) was a kid the same time as his sister Vanessa Kirby (31?).
Oh, and I guess they imply that Staham was secretly playing Deckard Shaw in the F. Gary Gray *Italian Job*? Does that mean that Charlize's Cipher is also *her* character from that movie?
