I'm going to look at Cap again when Alan Davis gets on pencils. If I like what I see, I may buy the trade. Despite my current embargo of Marvel, Alan Davis is one of my top all time favorite comic artists and I may not be able to resist a trade.
As for SA, it just didn't click with me. Bru is just much, much better with street level stuff. However, I don't think his SA was BAD. It just didn't grab me.
Bendis' Avengers, on the other hand, is B-A-D. There is an example of a writer that thrives on street level super hero stuff and drama but flat out fucking sucks on big stuff. I think I've pretty much hated everything he did with Avengers. I haven't read the title for a couple of years, but I 'Byrne-steal' the occasional issue to see what's going on and, yeah, it's still crap.
