"The Ultimates Vol. 1 - Super-Human" by Mark Millar and Bryan Hitch
"The Ultimates" is a great comic book, and Mark Millar is a great comic book writer. I'm not all that familiar with Bryan Hitch, but his work on this book is likewise impressive.
"The Ultimates" is a more realistic take on the Avengers, with the more fantastic elements of the Marvel Universe pushed into the background. The team seen in Volume 1 consists of Iron Man, Captain America, Giant Man, the Wasp, and to a lesser extent Thor. Bruce Banner/Hulk is present as the villain.
I don't want to give away too much of the plot. Suffice to say, Millar does some very inventive things with the Avengers. Thor is presented as a kind of messianic figure, Bruce Banner is the neurotic genius, and the relationship between Giant Man and The Wasp is the lynchpin that keeps everything else going. Both author and artist put a lot of thought into "The Ultimates," and it shows.
