Brian K. Vaughan is one of those writers that comics fans get excited about. When you've written the series Y–The Last Man and Ex Machina and created Runaways for Marvel (and then he spent a few years working on that little tv show called Lost), it's pretty easy to see why people get excited. His new book is Saga, and it is a great book. One of the best comics I've read so far this year. It's been years since Vaughan's written a comics, but he hasn't lost anything, and artist Fiona Staples is doing the best work I've ever seen her do (and I say that as someone who's liked everything I've seen of hers).
