Debatable overall, but not with respect to this film. Fact is, Tim Burton's credits are for producing it and for story and characters, which is primarily attributed to a poem he wrote ages ago about Jack, the dog and Santa Claus
only. Burton was on set of Nightmare Before Christmas for less than 10 whole days and that was spread between 5 or so short visits. If you know anything about the duration of these stop-motion productions, you'd know that is almost completely negligible. He was on a completely different continent during production working on Batman Returns for the entire time.
It's Henry Selick's movie with some inspiration provided by Burton. Burton just gets way too much undeserved credit for it.
I find it interesting that three-quarters through production Burton's name mysteriously popped up as a co-director of The Corpse Bride on IMDB. Seems shady to me.
