You would think that in a movie that has all of them for once, they'd all to get to do something.
I mean, would it be that hard to ask? What's the point of all of them being there if they can't beat down the weakest of those guys? I know it's a DBZ movie, so I'm not supposed to make too much sense of it....But come on.
We don't even see how Krillin and Tien get beat down, we just have those asswipes talking about how good Goku's friends are, but not really that good (hurr hurr, your friends suck)
And it's TRUE.
Perhaps I'm expecting too much of it? But it's like having a bunch of pencils, you sharpen them, but all but one of them break when you have to write something. Just throw the useless pieces of shit away.
