I happen to enjoy the franchise. I think that adding the Rock was a brilliant move. Sure it's over the top, but real men like action movies.
I will say that I have never watched Tokyo Drift in it's entirety. All I needed to hear, was that it didn't have Walker or Diesel, and added Bow Wow and some redneck no name. 
I will say that something is definitely missing without Paul Walker.
Here is my rule.
If I suspect the writers deliberately wrote it for people with an IQ of 80, I'm out.
And there was a very clear implication in that quote from Vin in the first movie.
"I live my life, a quarter mile at a time. For those ten seconds or less.."
It's all about saying that he is driving ten second or less cars. ALL about it. It's douchey as hell and I was out, the moment I heard it. If you go back and listen to it, he struggled with the line delivery because of how unnatural of a thing he was saying.
.. for the record, I was also out on XxX when Vin Diesel screamed "I live 4 dis shit!"
And to be clear, I like Vin Diesel in other stuff (riddick movies), I just don't like tribal tattoos or writing that isn't so much bad as written for dunce c.unts.
