Jesse, I only read it once, not long after it came out. But from what I remember:

I hate the art. The cover of the first issue is iconic, but everything else is so ugly as to be distancing. I give David Mazzuchelli (no doubt spelled wrong) and Richmond Lewis at least as much credit as Frank Miller for Year One

It's self-consciously "grim and gritty."

I hate the depiction of Superman as government stooge. It's just trying to reduce an iconic character into a simple-minded political division.

Having mecha suits and monster trucks misses the entire point of Batman. There's pretty much a direct correlation between how much a story (like many of the movies) emphasizes the car, jets, copters, bikes, planes, and other gadgets; and how much I'll think it works as a Batman story. (The Dark Knight movie's coolest scene was the chase scene, but it seemed to have as much cases of Batman being clever as of his just having cool tech. Plus, truck flipping.)
