The second one was too cartoonish, and the cameo by Vanilla Ice was a mistake.
Go ninja go ninja go!
And even though Casey Jones wasn't in the series that much, I just love is lines. "When am I going to break something!" Jones just wanted to smash things. He didn't have a personality!
I prefer the 87 cartoon series over the 2003 cartoon series simply because I grew up with it. Yes the 2003 series has a better storyline and is less cartoony, and more real to the comics, but like I said, I grew up with the 87 series.
Funniest turtle has to be Raphael simply because they made him this sarcastic joker that Rob Paulsen voiced. He had some of the funniest lines in the series. I prefer him to the real Raphael that has a major attitude problem and always seems to want to pick a fight with people, especially Leonardo. To me that seemed like another rehash of Wolverine vs Cyclops from X-Men.
But I also love Shredder, Krang, Beebop and Rocksteady, even though the mutant henchmen got old after a while. I love how Shredder and Krang always put each other down.
I also think a lot of the ideas the people had while making the cartoon series were rather interesting, something I don't think the creators of the Ninja Turtles comics would have thought of.
You have Krang, the Technodrome, Beebop and Rocksteady, Baxter Stockman as a fly, Rocksoldiers, Dimension X, Irma, Vernon, and Burn which were April's co-workers.
Plus it seems like the writers liked turning people into mutants. April was a cat, a fish, and an insect (wasp maybe). Irma was a rat and a moth. Vernon was a rat, turtle, and a spider. Burn was a turtle and a bee.
You can catch a lot of the turtle cartoons on youtube. I watch them all the time.
