Agreed. Thought he had a really good run. The magic/mysticism theme to his run never resonated with me though. I give him credit for attempting something different but it just never fit Spider-Man. I absolutely hated the entire concept that it was somehow fate and Peter was the chosen one in sense. One of the more appealing aspects to the character was that it could have been anyone that the Spider bit. There was nothing special of fateful about his origin.z
JMS on the bright side had some fantastic stories though during the run. His first Morlun arc is a flat out classic to me. His characterization for Peter was great and he also wrote one of the better marriages. He also did the impossible task of making Aunt May actually interesting.
All in all I liked his run especially when you compare it to what came after with Slott. However It can’t be ignored that he did write Sins past, the other and OMD. Just 3 absolutely atrocious storylines and one could make a strong argument that those 3 are the worst Spider-Man stories ever.
