Westworld really is a lot of fun. The sequel (Futureworld) isn't nearly as good, but does have an extended dance sequence with Yul Brynner which is really very strange.
What was interesting was the recurring theme of technology rising up to punish us for our hubris: Westworld, Planet of the Apes, automatic toilets.
I haven't seen Futureworld - I need to check that out.
I'm just now catching up with the last Depravity's Rainbow and I'd like to second Mike's love for Chris Whitley's Dirt Floor. I almost always have something by him on my portable media device, and more often than not it's either Dirt Floor or Living With the Law. Terrific record by a really underappreciated guy.
