I've seen multiple films based on Alice but never read the book. I finally have, and it's not bad.
The plot moves very quickly from place to place and character to character, but time seems to slow during each scene. The word play is amusing, but not brilliant (perhaps because I've seen too many film versions). I liked the book mostly because it sets the plot bunnies running. There is a reason for the multiple film/TV/book adaptations. It's chock full of interesting ideas and is short and spare enough to provide ample room for artistic license.
Definitely a good read to get the creative juices pumping.
