I know it might seem odd that I'm defending nostalgia, with my sig and all, but nostalgia has nothing at all to do with how bad something is. It's just something that brings back memories of your younger days. Thus, just about anything can be nostalgic to the right person.
It's when you let your nostalgia get the best of you that the problems arise. Being nostalgic for something doesn't make it bad, but it might blind you to something better.
