Batman: Year One: Tremendous. Anyone who tells you anything else is an asshole or hates comics.
Batman: Year Two Fear the Reaper: Not good at all. Passable.
Batman: Dark Victory: Loved it, but I am Jeph Loeb fanboy extreme. Agree with not reading it until after LH though.
Batman: Holiday Knights: Assuming that this is a collection of Batman holiday stories, skip it. The only one that I have ever loved is one where he arrests a criminal but gets gifts for his kids or some shit.
Batman: The Dark Knight Returns: Loved this and the much maligned sequel. Get both, and f the haters.
Batman: A Death in the Family: To me, meh. The "Joker has diplomatic immunity" thing is dumb, and Jason Todd was an awful Robin anyways, especially compared to Dick and Tim. If you can find it at a Borders and sit and read it, go ahead, but don't buy it.
Superman Vs The Terminator: Not a fan.
Superman: The Man of Steel: Tremendous. I came across this at a comic store the other day, and loved it. DC is also collecting the series and not just the mini, and I think that is worth checking out.
The Crow: Never read it. Movie was good
Any Sin City Novel(I do have The Hard Goodbye): They are all good to me.
Any Spawn: Honest to god, I have never read an issue of Spawn. Even in the 90's.
Skip them all and get all the Annihilation books.
