I've been sticking with some of the "new 52" (primarily Batman stuff, and a few others), but I can understand why many don't. For many of the books, the "feel" just isn't the same - and Jeff mentioning the whole Dick Grayson/Wally West thing brings up one of my biggest problems with it as well. I actually started re-reading the old "New Teen Titans" by Wolfman/Perez from the 80s after reading this thread and thinking about it the other day. Some of the DC stuff is still good, but some of it seems to be trying awfully hard to be "hip" (or whatever the hip word for hip is these days). Looking at the recent solicits, and seeing the cover to Green Lantern #0 is an example of that:

I trust Johns as a writer, and I'm sure it will be good, but the cover just looks like "he's got a mask, and tattoos, and a gun!" Although some of it was unknown or confusing to me as I grew up more of a Marvel reader, I still miss the old DC. Jeff mentioned some of my biggest problems with things too....the Robin(s) situation, Wally West, etc.
