As an aside somewhat inspired by this thread, I've always hated the "you only like this cause of nostalgia" argument. One, it implies that nostalgia is an invalid reason to enjoy something, which is just lame. Nostalgia is perfectly fine and pretty harmless, considering the list of things held up purely by nostalgia without having any other redeeming qualities is pretty small.
Second, and more importantly, it's part of this weird obsession we have online with tearing down things from our past. Especially as it relates to children's media, where most of the common complaints could be boiled down to "it was for kids and I'm not a kid anymore."
Does "Teenage Mutant Ninja Turtles" have flaws? Absolutely. Is it a little cheesy and silly? Yup. Do either have things suddenly erase the writing, direction, fight choreography, suit work and puppetry, and endearing performances? Nope. It's a good movie, and even if you disagree, it's weak to dismiss someone saying that just because they may have first watched it when they were 7.
