Comic book movies would be a different thing. I can't think of one I would describe as great. Nausicaa probably tops the list, and it's far from my favourite Miyazaki. Then Akira. If you're looking for live action, the '78 Superman and Burton Batman have some nostalgic value. Or in terms of more recent films, 2 Guns is probably the best one that comes to mind. Snowpiercer, Guardians of the Galaxy, Noah, The Fountain, Oblivion all worth a brief mention I guess, and the first 300 for that matter.
But anyway, yes, I was referring to books. Interesting how there's so little overlap between the US-UK tradition and the rest of the world. I think the cliche goes that whilst comics are a kids medium in the US they're taken more seriously in France and Japan in particular, but this is perhaps a little unfair given there is also the counter-culture tradition of Crumb, Shelton and co. in the States (fun to a degree) and also the Eisner 'graphic novel' tradition through Ware, Sacco, Thompson, etc, although I have to say I'm generally not very keen on that stuff with the exception of Maus (which is just very obviously the best American comic book ever drawn).
Arkham Asylum is the only book I've read from these lists. The art is okay but it's all a bit pretentious in a gaudy 80s sort of way. I've been meaning to read The Killing Joke for years but never got around to it (I've read Watchmen, it's okay). From these lists I might check out Black Hole, Saga and the Book of Lost Souls. You folks should definitely check out Taniguchi, will completely change your perception of what can be achieved with the form. A Zoo is Winter is out of print and a little bit expensive; after that would recommend The Summit of the Gods although unfortunately Vol.1 is also out of print and a bit expensive. There's a complete edition re-print of A Distant Neighbourhood coming out in December, suggest pre-ordering that if you're trying to save the pennies:
