I think part of the jabberwocky poem. Frabjousday is an essential part of the plot. I can't recall a scene where the entire thing was quoted. Maybe a section of it occasionally in different scenes.
"Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
The frumious Bandersnatch!"
This part sounds familiar, but I'm not sure. I haven't read "Through the Looking Glass" so I wasn't trying to find it in the movie. If I didn't know the movie was made by Tim Burton, I might have enjoyed it more, but I expected more.

On the flipside. I didn't think I'd like Sherlock Holmes, but loved it and found out Guy Ritchie(one of my favorite directors) directed it after seeing it. Had I known Guy Ritchie directed it before watching it, I might have been more critical. History sometimes affects my judgment.

If Tim Burton was a noname it might be considered a good movie, but I think it's average at best considering Tim Burton's other works.
