Six months in, and I think DC's line up is pretty much the same as it was before; specifically, it's not very good.
The trappings are different, sure. Character A got to Point B by a slightly different road than before, and the costumes are different (if by different you mean terrible.) To me, that stuff is irrelevant. I couldn't care less about the continuity being different...I completely understand why DC did this, and as a business decision it's hard to fault.
I think the two major problems I've had with the reboot so far are:
A) It didn't go far enough. IMO, this story should have been about the beginning of a shared universe. Every single book should have been about the beginning (or near beginning) of that character's journey, with every book starting from scratch. Instead, we have a mishmash of timelines..with some characters being completely rebooted, some partially, and those written by Geoff Johns and Grant Morrison not being touched at all. If you're going to do this, DO IT.
B) The books aren't very good. I know, this is subjective. And it's gross over-simplification. But to me, this should have been about DC putting their best foot forward creatively, and it's been anything but that. There are far too many substandard books for a project of this magnitude. I understand the need to do what they've done, but they threw the baby out with the bathwater. Also, so many of the books are so tonally similar that one feels as if many of them are completely interchangeable. The characters in Green Arrow could be substituted into the scenarios of Hawkman, and no one would have noticed.
So what do I like? Well, not much. But there are a few books that I think are strong. It's about the same amount of their titles I liked before the reboot.
I, Vampire - To me, this is the strongest book of the bunch, though recent efforts to bring it's continuity into DC's superhero world threaten to derail the momentum. This is a tragic love story first, and monumental vampire epic second. Joshua Fialkov is one of the stronger new voices in comic book writing right now. DC would be well served to pay attention.
Batman - This isn't a flawless Batman comic by any standard, but it's the best DC has right now. Scott Snyder continues to show that he's a better writer than he is a plotter, and so individual scenes are very strong, but the overarching mystery he's creating is a little weak. Some astounding artwork by Greg Capullo brings this book into the upper echelon of DC titles.
All-Star Western - Although I prefer the more typical western approach that Gray and Palmiotti had to Jonah Hex BEFORE The reboot, this remains one of DCs stronger titles. Like with I, Vampire, the insistence of bringing Hex into the DCU is short-sighted. A solid book, but unfortunately it replaced a great one.
Batgirl - This book has been woefully inconsistent, even though it's been written by one of DC's strongest writers. Simone seems unsure about who this new Barbra Gordon really is, and what we have is basically a retread of the concepts that Bryan Miller explored last year with HIS version of of Batgirl. The loss of the pre-reboot Barbara Gordon is probably one of the most disapointing changes.
Batwoman - If we're judging purely on art, there's no real question what the best book would be. Thankfully the writing is better than expected, though I can't say that the book has quite matched the standard it set under Greg Rucka's stewardship.
Animal Man - Probably the strongest of the bunch, and with good reason. It's rare that a modern superhero book can actually scare me, but this one does it almost every month. It's a magical epic that Lemire is taking us on, and it's a non-Vertigo book that happens to be more Vertiigo-like than most of that lines current offerings.
And that's basically it, at least in terms of the books I think are strongest. My Greatest Adventure and Shade are quite good. GL, and Aquaman are readable, but not essential. And the rest range from terrible to mediocre.
