(Not really calling you yourself out for this post, more for the thought that tends to stem from this attitude.)
Man, I hate this attitude so much. You see it a lot with Star Wars fans -- the fact that Lucas had the gall to make new Star Wars movies ruins their childhood. No. Someone making new movies based on a thing you like does not invalidate your childhood. They are helping make someone else's. Quom (I think) said it best, these are movies for kids. If adults can find something they like in it too, awesome, it did better than it had to. But I also have spoken to a lot of kids who really like the prequels because that's the Star Wars that they grew up on. And, in a few years there will be a new batch and that's awesome for those kids.
What? Were did I say my childhood was ruined by this? I just said I would be disappointed because nothing can live to my ridiculous expectations because I adored the films as a child. I know you were not calling me out personally, but still,. ;(
