Yes I'm 38 years old and just now reading this book for the first time. I'm sure there are hundreds of books I didn't read as a kid that I probably should have. As for this one, it was very enjoyable. I probably would've loved it as a kid just for it being so strange and weird, but as an adult, I love most how ironic it is. The word play, the whacky hijinks, Alice's existential crisis, and just watching Alice try to figure out how to Escape the Room she first lands in was a lot of fun. I never saw the entirety of the Disney movie either, just bits and pieces. I've only seen the Johnny Depp movie, which is post-Alice in Wonderland, in full. Why I did that, I don't know. I must've been feeling in need of punishment for some transgression at the time.
It was fun reading a classic like this, which I've absorbed a lot of through pop culture references, but have no real clue what to expect of the actual book. It was fun, easy to read, and certainly something that both children and adults can get something out of.
