When I think of the phrase "old school Ninja Turtles fan" I think of those people that were with the Turtles from the beginning. We saw it grow and mature and expand in ways we never thought.
Unless you've been there for the entire ride - and what a ride it was - I don't consider you "old school."
It's different for different people, too. Some people are "old school" in the comics; others, like me, are "old school" in the cartoon. Whichever it is, if you've been supporting the Turtles since the beginning, you're "old school."
Not that there isn't hope for you non "old school" fans. Some of you jumped on the bandwagon, which is great. And when this new cartoon comes out, we'll all be able to say that we're "old school" fans of the show. This younger generation of Ninja Turtles fans will look up at us in awe. We'll be able to say, "Well, kids, this is what the show used to be. Look how much it has grown."
We'll rule this planet!
