I am not sure what I can add to what has already been said.
I love horror games and TBoUH is one of the best source books I have had the pleasure to use in a while. Plenty of ideas here for lots of different games.
I like to think of horror as not just as a main course, but also a spice or a nice side dish to regular games. I dash of horror in your Supers game, a pinch of it in your FRPG, a nice horror sauce over your Pulp game. This book has enough several years worth of meals.
