I really enjoyed it. The main character is played by Steve Yeun from The Walking Dead. It's also got a pretty stacked cast - JK Simmons, Sandra Oh, Walter Goggins, and Zack Quinto are all have major roles. Seth Rogen, Mark Hamill, Jason Mantzoukas are in it in a more minor capacity. Oh, and Britta's in it as well.
If you do decide to watch it, give it til the end of the first episode, you'll probably know whether or not you're hooked by then.
If anyone was interested in the comics, they change things up enough in the show that I don't think you lose anything going through the series. Actually, in a way I think Kirkman is making improvements here and there since the show is essentially him getting to write it all over again. Plus there's also been fun easter eggs.
