If anyone's interested in trying out Marvel Comics, a bunch of the series are starting out with #1 in October/November, under their Marvel NOW line.
Basically, a bunch of series are going to react to the events of Avengers vs. X-Men, an event that includes a 12-issue miniseries (#11 came out last week) and affects many of their titles. So at the end of it, several series, most notably those that directly implicate the Avengers and the X-Men, are restarting at issue 1, or are starting new.
As a result, it might be a good jumping-off point. I myself haven't bought Marvel books by the issue before (only the occasional TPB and library reading), but I'm checking it out.
I personally will be buying "All-New X-Men" (the original 5 X-Men coming from the past into the modern time), "Thor: God of Thunder" (replacing The Mighty Thor), "The Indestructible Hulk" (replacing The Incredible Hulk), and "Uncanny Avengers" (new, a team made of both Avengers and X-Men).
But they're also doing Captain America, Iron Man, Fantastic Four, FF, Thunderbolts, Deadpool, a couple of other Avengers and X-Men titles. For more information, check out the wikipedia page: http://en.wikipedia.org/wiki/Marvel_NOW!
I'm also reading Captain Marvel. The character of Carol Danvers (formerly Ms. Marvel, Binary, and Warbird) has taken on the mantle of Captain Marvel, and thus is more prominent. I loved the old Ms. Marvel books from the 70s (got the Essential Ms. Marvel book and loved it!) so I thought I'd try it out. It's really well written, and the art is really cool. Reminds me a bit of the painted style in the Star Wars: Blood Ties books (but better).
