Awww man... what a thread!
I love comic novels. FAR more then normal novels. My collection is growing fast.
Where to start...
Alan Moore. I love him. From Hell is an *amazing* book. Watchmen is so far ahead of the movie in terms of story and intensity, that its embarrassing that they even tried to film it.
Garth Ennis. Both Preacher and The Boys are fecking awesome. The former is god damn disgusting in places. I love it. The Boys is the best collection of super hero books ever. Paints them to be a bunch of nasty wankers, as you *know* they would be if they existed.
The Walking Dead is absolutely gripping. As far as storytelling go, it pisses on the TV series from a great height.
I'm currently reading The Dark Tower from Stephen King. Not the best story ever, but the artwork? Man O man... the artwork is glorious. If imagery is your thing, you absolutely HAVE to check them out.
The Filth, under the Vertigo label, is some of the most twisted, perverted, confusing shit Ive ever read. Been through it 3 times and im still confused. Always leaves me feeling really disturbed.
The darker side of Batman is also fantastic. Arkham Asylum is a twisted book with twisted artwork.
But, my favourite, without a shadow of a doubt: Transmetropolitan. The whole thing from beginning to end ( 10 books ) is absolutely top draw entertainment. If anybody reads it and doesn't laugh all the way through... well, those people have no brain.
God, ive only just touched on the series of books. Ive got ao many individual books that are also awesome. I'll leave it here for now!
