Technically Neverwhere by Neil Gaiman could be considered an Alice In Wonderland knockoff...
As for Wonderland and the whole outlook Toby has on it, I have to say I politely disagree with him. Even as a child I felt that Wonderland wasn't really meant to be all bright and cheerful for some reason or another. The elements it shows are really darker than a lot of people consider. In fact, I blame Disney for shedding that bright, cheerful outlook on it rather than Tim Burton doing the other way around.
My views MIGHT be a bit askewed, some would say, due to American Mcgee's Alice, but, I rather liked that portrayal. I'm sure Alice would have been sent in for psychological quackery in her time and age if she had told anyone of the world she experienced, and psychology during that time period was really in its infancy as a field, so not was there vast amounts not well understood, but treatments would be considered simply inhumane by today's standards. It might have been nonsensical, but I didn't think it was really all that cheery. The Duchess, who not only neglected her child-an infant who was suffering from a cold-but also beat it for its woe, and wished to consume the Mock Turtle, an intelligent, sentient, talking being.
The Red Queen, with her short temper and a willingness to have the head removed of any she perceived to have slighted or gone against her in any way. Subsequently, the fear such a tyrant could cause.
The allusions to drug use, such as the caterpillar smoking his hookah and the mushroom that allowed Alice to grow and shrink as she consumed bits. Perhaps minor, though, considering mannerisms and relatively lacking medical knowledge in those days.
I would say that Carrol's true nonsensical literature had lain with Jabberwocky and The Hunting Of The Snark.
