Because I felt that Avengers #24 was a resolution, whereas this didn't feel resolved to me because I still have too many unanswered questions. Maybe Hickman did answer them, but not clearly enough for the ending to be satisfying.
Call it what you want, but, it clearly was a phoned in, recycled storyline. It made the whole AIM scientist supreme thing a big joke
It just looked like to me that Bendis was making this stuff up as he went along as opposed to Hickman whom had a plan for everything from the beginning.
I really would suggest you go back and read this from the beginning, because everything is really explained in detail. Like I said earlier it's a much more efficient storytelling style than most other Marvel books, very little pandering and fluff.
