I'd probably have enjoyed it more if it had indeed... "sucked balls".
Ok, now that that's out of the way.
I liked the use of thought bubbles, and i'd like to see that stick around. I liked the characterization for the most part.
Though Jenkins and Bendis really need to get together and sort out the Sentry deal. Since the NA Sentry arc, Bendis has been writing him with a completely clean slate with no one remembering him, and him only just getting the feel for superhero-ing again. Whereas Jenkins has written him as completely confident, taking lead, the people loving him etc. etc. It's kinda stupid.
I liked the Ultron twist. The art's ok. So far it seems like the lineup could make for an interesting team.
So yeah. I liked it. It was a fun read.
