So far I've gotten Flash, Batman, Green Lantern, Aquaman, and Blue Beetle. I'm still waiting on Justice League, Action Comics, Detective Comics, Teen Titans, and Superman. I honestly don't even know if I'll get JL or AC since those came out weeks ago and still haven't arrived.
Anyway, all the issues I've gotten so far have been great, with Blue Beetle probably being the weakest if only because it doesn't show off BB in action at all. Flash, Aquaman, and Batman have been excellent, though.
If anyone wants an avid comic reader's review on the whole series of "The New 52" then I strongly suggest you check out Linkara's reviews called "That's All I'm Saying" on his blog. [http://atopfourthwall.blogspot.com/] Though he's not claiming that his opinions are absolute truth, he still provides good insight and recommendations for new readers.
All in all, it seems like at least the mainstream heroes and groups comics are off to a good start. There are some issues that aren't good (according to Linkara), but most of the ones people have actually heard of seem to be ranging from good to great, which is all I hoped for.
