First off, I'm not a big fan of Adam Driver, but he did show OK as Enzo I thought.
They all fake accents (Penelope Cruz plays the Italian wife - also still hot ), and so on, but did a fair job for the most part.
There is some decent situational drama. Not sure how much they exaggerated things, however, things do play well to the overall story.
Cool driving/racing scenes. Very Ford/Ferrari movie-esque. Still different. Nice old school location scenery, albeit CGI. You get a little jaded to fake lines and colors after a while. They did a good job.
