Been reading A Game of Thrones and it has been a pleasant experience so far. I rather like the prose, and it doesn't overcomplicate things (though it seems a smidgen clunky in parts), but I think watching S1 of the show helped get into it somewhat.
Though I have been reading it on and off because I'm liking my Kindle, and its ability to display PDFs, so much that I find myself drawn to screenplays/scripts as well. Finished Munich, which I hadn't watched in ages and remember liking more than I did the script, and have been working through Chinatown...because it's fucking Chinatown, man.
I did read The Big Sleep screenplay but it was an older inferior draft which also left me a little confused while reading (because I was expecting a scene that never appeared and then the finale was so sudden). I'll probably buy the Chandler collection available because the individual Kindle editions are a rip-off and I kinda want to see how the original novel ended...
