Jesus, too many to mention and I'll edit the fuck out of this post later so keep your peepers peeled:
The Master & Commander novels by Patrick O'Brien - after reading a few you come to regard the characters as close personal friends. A living, breathing world that you can genuinely feel a part of. Utterly beautiful.
Father Ted - so good Spanish housemates have watched with me, laughed, sent box sets to their relatives.
Laura Viers - American indie songstress that is the latest incarnation of clever singer-song-writer lass I love; Kate Bush, Tori Amos, Tanya Donnelly etc.
Twin Peaks + David Lynch stuff - Not seen the second series of TP, but he's the only director who seems to 'get' nightmares and dreams. The diner scene in Mullholland Drive is to date the most terrifying scene I have ever seen not in the movie Threads.
The Wire - so good it hurts. Literally. If you're not listening to Charlie Brooker and others who have taken great pains to explain why its so good, then you're an idiot.
Clever funny cute indie girls with brown hair called Sarah or Alice or Jane - I'm only human.
Altered Images - They're awesome, you're wrong.
G. K. Chesterton - The Napoleon of Notting Hill and The Man Who Was Thursday would have been adapted into movies already if Hollywood had a genuinely romantic and adventurous soul in their body. Quixiotic novels that explore the soul and offer up beautiful poetic and very funny surrealism with lots of Indianna Jones stuff thrown in. Thursday is like Monty Python meets Brazil meets Indianna Jones meets James Bond meets the Bible meets The Invisibles meets Father Ted meets everything glorious and true.
Jonathan Strange & Mr Norrell - there was a minor backlash against this impenetrable, hefty tome involving a gloriously complex faux historical magical adventure of two squabbling magicians seeking to reintroduce the Raven King's magic to England. Ignore it, the book's awesome and I shall never forget the journey.
Twisted by Design - perilously close to a scene now in Cardiff, despite one that only commands an average of 50-60 people attending. Still, I love this influential, Los Campesinos! referenced indie club deeply. Yay for Gary Twisted!
Calvin & Hobbes - oh, do you really need to know. Go read it, now. Even if you have before.
Captain Star - nobody knows about this cartoon despite it being the best cartoon since anything Chuck Jones did. Richard E Grant and Adrian Edmondson star. Captain Star is a narcisitic Captain in a starfleet stylee organisation, who's sole mission is to find new planets and civilisations, name them after himself and sell them things.
Eerie Indianna - see Twin Peaks and Twilight Zone - but for kids! And equally ace! (Don't watch the remake though, ugh.)
