There's a scene on a quinjet that sums up this comic pretty well. Fairly unfunny banter between too many characters drawn poorly on the way to fight a fairly unthreatening threat. Bendis is capable of writing some fantastic comics, and even some not-terrible Avengers comics but this was not one of them. Too many characters feature here for any of them to get a strong presence on the page and the only one of them with a distinct voice was Namor, whose opening narration featured some very clumsy hyperbole and a baffling plot choice. If no-one would think to look there, why bother taking the gem away? Oh and did Romita's art live up to his own standard?
No, Romita really brought the fug on some of these pages.
The big danger room spread: fug.
Three characters underwater: fug.
The Hood: fug.
Awkward banter: fug and unfunny.
No-one involved in this comic is a bad creator, but somehow together they are far less than the sum of their parts. That said, the bits with Falcon, Black Widow and Moon Knight? They were great. If only they weren't part of a different comic. One with maybe a scrap of merit.
