None of this is "killing any of my childhood", the original comics, movies and tv shows are all still there. Just take all of this as a reinvisoning and you don't have to watch any of it. Let them make whatever trash they want, its not like he's going back into his old movies and changing tons of things as an afterthought.
I'm a die hard Ghostbusters fan, if they make a thrid one with a new cast, fine. It doesn't tarnish the original work and everything I loved about the first two and TV show doesnt change.
Lower your expectations in the theater and life will be a lot easier. People build up what they want to see and when it doesn't show up, its like some sort of diservice has been done. I didn't make it, it sucked, oh well.
The new Nickelodeon cartoon looks good. I like the art style they went with it and the fact that they asked Rob Paulsen back to do Donatello's voice. I don't know if I will actually watch it, but it looks like it's a good cartoon nonetheless.
