I was personally very unhappy with gloomhaven's decision to spread the content out so wide. I think they could have structured a much stronger game experience if they just focused on a core 10 to 20 modules versus the over 100 they have.
Not to say they couldn't include more modules, but when you're trying to progress a storyline it's really frustrating to have multiple sessions (most many hours long) in between you a plot development.
