Is there something wrong with me still enjoying these things at 21?

I enjoy comic books, video games, and I even enjoy going down the toy aisle and get something if I like it enough. I'm considering getting some old figures just for their cool factor and I even enjoy watching old episodes of Power Rangers, just to feel nostalgic. Is that a bad thing at my age? Movies like "Knocked Up" and "The 40 Year Old Virgin" are showing it isn't.
