Thought it was funny as hell. Didn't really care for Gisele dying, she was particularly awesome in 5, and they could have just as easily done some sort of falling out between the two of them instead of just killing her off to maintain continuity with Tokyo Drift. And given the retarded shit that people tend to survive in movies like this, I find it completely impossible to believe that she died just from falling off the cars onto the tarmac no matter how fast they were going.
If Letty could survive F&F4, I see no reason why Han couldn't have managed to survive the crash in Tokyo Drift, they make a point in keeping the camera focused on Statham when he's walking away and don't show Han at all.
