It's funny, most critics and Walt himself felt they didn't get the tone right for Disney's Alice. I think many felt the humour was more slapstick than Caroll's use of wordplay, etc. It was one of the few of his animated films he allowed to be shown on TV, and of course was released for 16mm rental (and then apparently pulled when they realized that many colleges were renting it because they saw psychedelic/drug influences, similar to Fantasia--ironic because by the 70s both films had re-issues that had very psychedelic posters seemingly selling that point). I think Walt also said he felt Alice was never sympathetic.
But... being a big Alice geek as a kid, I really love the Disney version too. I guess it is different in tone to the novels--there's no sense of any of the slower scenes on a golden afternoon, despite the song, etc, but as a film it's always been a favorite of mine, and it seems people have liked it more with time. Back in the 80s as a kid it was likewise one of the first Disney films you could always find on VHS and I watched it so much that I think I could still hum the entire background score (the Alice in Wonderland dark ride at Disneyland is also a must for me even if I've had friends balk at the idea of riding in those caterpillars...)
Much harder to defend but I also have a nostalgic soft spot for that "all star" Irwin Allen miniseries version--I must have been five when it aired but I remember what an event it felt like and I can probably sing most of the Steve Allen songs (of course it's hard to beat Carol Channing's Jam Tomorrow). Adding the Jaberwocky as a villain and not just a poem drove me crazy even as a kid, but it seems like a lot of adapter feel the need to give Alice some sort of story drive like that (I know even Disney contemplated using him as a character).
Which of course was IMHO disastrously handled in the awful Tim Burton version if you can even call it an adaptation, To turn it into some sort of quest fantasy just made no sense to me and I think it's a mess of a film (more annoying is how many people I know who somehow believe it's a faithful adaptation--to be fair Burton never claimed it was).
I've seen a number of others but not for a long time. I used to love the PBS filming of the stage version as a kid as well, but barely remember it (except that there was some behind the scenes thing where you saw one of the actresses smoking which shocked me as a kid who thought smoking was very bad indeed). And I've seen the 30s all star version which is slow but has great designs and some fun performances. I also remember a British version with songs and music inspired by Indian music (?) and the creepy stop motion one by Jan Svankmajer (as well as kinda Alice related, Dreamchild which I found interesting but flawed especially when it tried to be based on reality). It does seem to be one of those stories that's very hard to adapt to the screen, but people find hard to resist.
Oh and of course there's the brilliant Betty Boop in Blunderland!
