Dude, maybe it's me but I thought Tokyo Drift was the absolute bottom of the series. I mean 2F2F was kind of bad, but then TD totally sucked for me. The actors were terrible (even by F&F standards), the only redeeming quality was Sung's character. And that sweet orange RX-7? he was driving. Maybe it was because I had already seen the live-action version of Initial-D but I felt like that was a far better "drift-racing-type movie" than TD... even if that one did also in hindsight have terrible acting as well, the driving sequences were so much better. I do feel like with F&F and F5 the series picked up again, I mean it had to after hitting rock bottom with Tokyo Drift.
On another note, what I do fear with the release of this movie will be, the increased po-po attention to import cars and modified cars in general. If the BRZ gets some star attention on the big screen, I dread being pulled over shortly thereafter by LE who are thinking in their minds, "oh there goes one of them F&F type cars, let's see what they have under their hood, or in their trunks..."
