The most fascinating film in the franchise. Some call this one the most underappreciated Fast & Furious film, I'd say it was the one with the most potential.
The opening HS race is complete s***, but once we get to Tokyo the film takes a culturally observant turn that I found rather fascinating. Even the language barrier is communicated through driving; Sean (a young adult who always solves issues the "American" way) is a good enough driver, but to learn how to drift is like learning a new language. Plus, Justin Lin brings a vibrancy to this franchise that would only get better from here.
It's just a shame that this was Sean's story, as he is arguably the least interesting character here. Everything that is thematically fascinating is funneled through the character of Han, and I wish it was more his story. Thankfully we get more Sung Kang in future films.
