The reason is because the gameplay and looks of it looks so much like Smash Bros. Brawl that it makes you believe Sony is trying to make a parody. Hell, even the font they use for the game is the same as Smash Bros. Brawl.
The gameplay itself looks like absolute garbage. Animation looks terrible, there's no response when you hit a character (you just flow through like you would hit butter) and no one seems very fond of the way you defeat your enemies.
So far the game is made for failure. But it's still in developement, so hopefully a lot will happen.
Edit:
Kamiya has spoken! All praise one of the video game overlords.
