Caught this with the wife yesterday. Incredibly fun movie, and worth watching on IMAX. Vin Diesel seemed to be channelling his inner Stallone for a good part of it (slurring words, massive fistfights) and it offered closure to a number of characters from 2 Fast 2 Furious and Tokyo Drift, but still left the door wide open for a sequel.
This, I think, was my least favorite episode of the season. The new kid being a jerk to everybody didn't do much for me (although Dean going apeshit on him was great), and I thought the biodome scene went on just a bit too long.
