You can't go wrong with a good bit of Terry Pratchett. There are few other authors who can capture the human condition in such a funny yet easygoing way.
His Dark Materials. Goooooo Atheism! Except not really. There's actually nothing in those books that precludes spirituality or the existence of some animating force, they just point out the absurdity of assuming you have the slightest chance of knowing what such a force might be thinking, and the harm that can come if you think you do.
Titus Groan, Gormenghast. Gothic Grotesqueries, lyrical writing, leaps of the imagination, breathtaking imagery.
All the Sci-fi short stories ever and then some. I have 100+ anthologies and building all the time. The soul of SF is the short story, and some of the most profound and beautiful imagery and ideas are found here. In no particular order, Brian Aldiss, Paulo Bacigalupi, Tony Daniel, Geoff Ryman, Ray Bradbury, Harlan Ellison, Ursula Le Guin etc etc etc
Been getting really into some of the premium cable dramas lately. Mad Men, Breaking Bad, Spartacus: Blood and Tits, even goofy stuff like True Blood and Dexter. Its great to see such high level writing and acting get the space to breathe that the 13 hour format lends.
Miyazaki (I'm a bit behind actually, need to see Ponyo and Arietty), Gilliam, Danny Boyle, Pixar. Bits and bobs from all over really.
Anything. Well, anything veggie, but I'm adventurous, I'll try anything and before I went veggie I had basically no qualms about trying anything once. The exception is super hot spices, they just hurt, and I can't stand beer.
Environmental issues (depressing!) and how to make a practical difference (hopefully less depressing!)
