When Dom collapses a parking garage with his foot, jumps between three buildings in a car, jumps across bridges to land on the hood of another car fifty feet away while catching his girlfriend midair with no injury, drags and rolls bank vaults with precision, punches through concrete and steel, plants bombs on helicopters with a car in midair, and jumps out of exploding planes in a car, it's pretty much already a superhero movie, and the addition of Hobbes and Shaw just made it even moreso. Everyone in the movie is capable of making speed and trajectory calculations faster and more accurately than a supercomputer, capable of surviving beat downs with steel pipes and stabbings and bullets and explosions unless you're the designated death of each film, capable of hacking anything anywhere instantaneously, and other stuff that your typical street racer turned secret nuke stopping government asset would know.
Plus, they've already gone scifi-lite with the God's Eye super-surveillance system and the mass car hacking and control system and the super-duper hacker flying around on their own AWACS plane, so this is just embracing the utter insanity of the premise and taking the next step.
My issue is not with the over-the-top ridiculousness of it all, because it's always been thus, and especially for the past four films, it's that they're getting rid of the familia to focus on Hobbes and Shaw alone. I get that there was some friction between the Rock and Vin Diesel, but it's not the same without the whole team there, and I hope they get them back in future installments.
That being said, Idris Elba is always awesome as a good guy or a bad guy, and generally elevates even the most ridiculous stuff he's in, so that's a plus. And with the way the villains go on to become good guys in some cases, regardless of how many police and military personnel they have murdered or that they blew up your house and killed your friend and tried to murder your sister and nephew and best friend/brother-in-law, it's possible that he might turn out to join the extended familia because he has a heartwarming background story.
