Yesterday we went to see Fast Five along with, apparently, everyone else in the known universe. All you really need to know about this movie is that it is a sequel to the previous four Fast and/or Furious films. If you don't want to see it based only on that bit of information then, chances are, you don't want to see it at all.
Other than that, all you need to know is that the movie consists of The Rock Dwayne Johnson sweating a lot. Cars crashing a lot. Stuff blowing up a lot. And the entire audience suspending disbelief a lot.
In other words: I can't wait for Fast Six. (Hint: don't miss the teaser for that installment during the credits)
