I liked turtles when it came out, but now i think the original series was a little silly - too self referential and shredder was such a doofus. The first film i liked (the movie origin of splinter was hilarious).
The second movie had Vanilla Ice - ugh! the third movie was poo as was the live action series and i think some other cartoon of it.
The most recent incarnation howeveer seems to be ok i think i even saw a lightsaber in it!!:D
