Reasons why this shouldn't exist:
That really, really sucked. As a reviewer, it's my job to tell would-be viewers why that sucked so they steer clear of it. I'll do this score by score.
Graphics: It's a stick, a board with no fill-in, with an isometric view of a halfpipe with no fill-in. Yes, that's right. Just outlines. At one point in the video a random stream of red appears above the stick's head for no obvious reason at all.
Style: The slow framerate, generic music and pathetic attempt at a joke killed every ounce of style this video might have had.
Sound: Generic, short music and absolutely nothing else.
Violence: Why does the red come out of him before he gets hit by the board?!? And that's the only moderately violent thing in this video.
Humor: Ooooh, he gets hit in the head by his board in a move that would make a physicist cry. No, that can't actually happen. And that's the humor.
Overall: I heard they're making a site dedicated to this flash. It's called flashesthatsuck dot com. It's a sheer mockery of both the skating community and the hard work people put in to give us all quality flashes here on Newgrounds.
