The Cove: 8 out of 10.
Now don't get me wrong, The Cove is a great documentary about some bad shit going down in Taijii, Japan. I really liked it. But The Cove won the Oscar for Best Documentary, and it's not that good.
But you should see it, cuz it's good. Unless you really, really like dolphins, in which case this is a bit of a snuff film.
