If you want to do the homework, I'd start with 5, then 1, then 4 then 2 and 3 in terms of material for this movie, and in terms of quality I like the Vin ones better (1, 4, 5, 6).
But really, it's not hard--Vin is a drag racer who led a bunch of car thieves (including his GF--his sister is an excellent driver but doesn't steal or race) that Paul Walker went undercover to bust and ended up on their side. They accumulate more folks into their family as they go along, and Michelle Rodriguez (Vin's GF) is killed in #4 (which is a prequel to #3). At the end of #5, in which they went up against the Rock, they totally intend to retire...
I love the disclaimer at the end that pretty much says "PLEASE. For the love of god don't take any driving tips or tricks from this. They are professionals, and also this is fake as all shit."
P-C, I am not even sure if the collateral damage in this movie is worse than what the good guys caused in #5. When they drag that safe through...Miami, was it?...there's no way a shit ton of people who were just minding their business didn't get killed, never mind the property damage. I can't think of another franchise that fucks up more passers by than this one. It's now a laughing matter for me.
Also, while it didn't match the climax of Fast Five, it was still a wonderful moment when I realized THEY DRAGGED A PLANE DOWN WITH THEIR CARS.
In this one, the plane is about the only thing, including the people, that can't fly. That moment got applause throughout the room.
Oh, and the fight scenes are pretty fun--I hadn't realised Gina Carano is in it, and my only complaint is--if you have Gina, pull her hair back. Let us see that it's her doing all those things. Even if the person she's fighting against is doubled,, enh, whatever. Cash in on what you have. This is also much more her acting speed than the Soderbergh acting vehicle.
The Rock, aka Samoan Thor is totally ridic, in the best possible way. He's precisely the size of huge that I don't think is preposterous, largely because he can clearly move well. The other big guys in the movie looked sillier. They just didn't wear it as well.
For the kind of movie this is (popcorn+steroids) I think it did exceptionally well by women. There are, what, four women with action roles and no screaming or or random "chivalry", no couples are making helpless cow eyes at each other, and no one's choices or genitalia call into question their competence.
I am so freaking delighted that they are going to add the other famous movie driver from the past decade or so to the incredibly long-running franchise. Paul Walker has been in all of them, right (oh, wait, not Tokyo Drift)? Which is good for him, since he really really can't act.
(I am so fucking sad that Han seems to be dead. I didn't see that coming, and I hope it's not true. Come on, 7!)
