    I've seen a couple of the other Fast Furious films but this one is definitely best. Dominic Toretto (played by Vin Diesel), Brian O' Conner (Paul Walker) and Mia Toretto (Jordana Brewster) are planning to steal $100 million from businessman Hernan Reyes (Joaquim de Almeida). At the same time, agent (联邦特工) Luke Hobbs (Dwayne Johnson) is chasing after them. The story's pretty fast-moving and the car chase at the end is amazing.

    Well, if I'd known it was an action film, I wouldn't have gone to see it. I mean, I can't stand action films. And I'll tell you another thing – I can't stand Vin Diesel. I mean he can't act to save his life. The film would have been much better with someone like Mau Damon or George Clooney. The only good thing about it was the soundtrack (电影配乐) which was pretty good. And I won't be going to see any other Fast & Furious movies either!

—Zoe

    Well it started off all right, but the romance between Mia and Brian was a bit inadequate (不足的) and the whole thing lost its way. It was as if the director couldn't decide whether he was making a thriller, an action movie or a romantic comedy (喜剧), so he ended up making none of them.

—Mario

    It was amazing! I can't believe it was really over two hours long. It just flashed by. The direction was superb; Justin did a really good job. And the acting was great. I know Vin Diesel isn't going to win an Oscar or anything like that but he's good at what he does. And the plot! I laughed out loud quite a few times. The funny thing is, I wouldn't have bothered seeing it if my friend hadn't suggested going.
