Well first of all I never watched the Turtles, so I have no bond with the characters. But I guess the Turtles are better known than most Nintendo chars.
Secondly I love the Knock Off play style. So much fun trying to jump back. Or meteor-smashing people. I never had much fun with SSB's stamina mode.
Thirdly the glowing characters freak me out.
Fourthly... it just looks plain boring when I watch those movies. It's hard to pin down, but I think it might be too slow, and the attacks don't seem to hit very well.

But again, I suppose I'm in a minority here. You'd expect the SSB guys to do a great job at this, so we'll wait for the reviews.
