Bagley's art for MIGHTY AVENGERS looks alright, although naturally he's not in his prime from the early 90's, some 15 years ago, and relies on the colorist like many artists these days to spruce up. Still, he does good bright superhero work, so he is a good fit.
What I always find "great" is how Bendis maintains a tight knit continuity with his own books and is much more willy-nilly with the continuity that anyone else establishes. I mean, sure, most writers treat their own titles as a pocket "universe" of sorts and interconnect subplots/details sometimes (Dan Slott and Robert Kirkman come to mind), but most of them also show the same curtesy towards other writers' work, while Bendis, whether you love him or hate him, picks and chooses what he will run with and what he will either outright retcon or passive-aggressively retcon by omitting. Naturally, as the #1 selling writer at Marvel, anything he does is supposed down the line, while the works others do, sometimes with his own characters, is barely noticed.
Example: as soon as Purple Man became hot **** in ALIAS, suddenly every book in Marvel took heed, treating him as if he was always some purple Hannibal Lector instead of a F-List Daredevil castaway. Meanwhile, in DOCTOR STRANGE: OATH, BKV had Dr. Strange allow Night Nurse, a character BENDIS INVENTED, move into the Sanctum and date Strange, and Bendis has been writing Strange in about 6 issues of NA without a mention of this point. When and if he finally does acknowledge it with either an on-panel appearence or a throwaway line, Bendis, of course, will expect his penis to be slurped for it.
The symbiotes suffered a massive drain in numbers from Venom during the 90's and even got a bio in a Handbook Update from this year, but whether Bendis will insert any of this (or an editor will remind him), or he will go about his merry way without any care as to getting history or powers right (like with Carnage in NA #2) is anyone's guess.
Frankly, I had enough of symbiotes in the 90's. Marvel played them out, like that annoying friend of yours who apes the same god damned 3 lines from that CHAPPELLE SHOW skit. I am not looking forward to more of them.
