Worm is great, even perfect if you skim between Arcs 16 and 27 (with exceptions for some genius stuff in 20 and 22). There's just a lot of filler and bad decisions due to being one of the first serial works, and the beginning and end were far more planned out than the rest.

On the other hand, people say Practical Guide to Evil is similar, and it is, cosmetically, but I found it much more "Young Adult Fantasy" than anything else.
