I'm exactly the same with the novels. I loved the EU up until the Visions of the Future books, then it all started to get silly.
I do have some faith in Disney though. They make great films, and I thought the Avengers and most of the PotC films were good. So. There is some good, but basically, I wish they'd just leave it all alone.
I agree, The Avengers was pretty good, I'm a fan of Joss Whedon. He did pretty good, and add the fact he worked for Marvel briefly as a writer for the X-men series. Out of the all the PoTC movies, i think number 4 was my favorite. I'm sort of on the fence, kinda apprehensive, but i will give them the benefit of the doubt and reserve judgement until the finished product. I just wish they would stop tinkering with something that was good the first time around.
