I, for one, think it's great but the main problem is that they haven't developed him enough.Ultimate Miles sucks. It's been 17 issues and the kid is still a total noob with no defining characteristics. The book is coasting on the Spidey name, and the support cast is very unlikable. I miss Peter Parker back when his supporting cast was Kitty, Iceman, Human Torch, Gwen Stacy and MJ. So good.
Out of 17 issues, how many of those were SHIELD or Peter Parker-related? At least a half if not more.
If you consider that he only had about 8 issues "to himself", it's not surprising he and the supporting characters aren't well developed.
I think it could be as good if not better than the old USM if they just start focusing on Miles and not constantly bringing back old characters and doing cross-overs.
Kind of reminds me of what happened with Apollo Justice.
