Thankfully saw this in a matinee. I seem to remember these movies being entertaining, and kinda stupid, but not laugh out loud stupid. Scene after scene was so hilarious, the audience (of like ten people) couldn't stop cracking up. The plot, the dialogue, the acting -man. More power to them, I guess, cause they made a shit-ton of cash, but damn, they're not even trying anymore.
The climax of laughter came when Dom launches from his crashing car over the guardrail, catches Letty mid-air going 70+ mph and lands on another car ...without a scratch! Then of course there's the 70 ton tank somehow being flipped by the 2 ton car getting caught up on the overpass because of the "magic cable". I laughed so hard I cried.
Dom's flying headbutt during the Russian transport plane brawl was great in a slapstick way, too. Actually, now that I think about it, the series seems to have devolved into a live-action anime. I hope the next one involves flying mecha racing in Japan with Jason Statham surfing on top of them kicking people to death!
