For those who never liked Nightbreed I will say that I hated the film the first time I saw it. I was bored and felt the story was disjointed. For some reason years later I picked up the book "Cabal" and enjoyed it thoroughly. After that I decided to watch the film again and noticed how much of the story was actually missing, plus with the understanding of what was meant to happen I found myself enjoying it a lot more.
So for those who never liked it I suggest reading the book if you have the time.
