The Encyclopedia is very awesome... but no... you want to save it for last... it is the bonus disc for all the Nightmare on Elm Street movies so it will contain spoilers for all the movies.
That being said... I love how the disc is set up... where you actually play a game with your dvd player's remote... exploring Freddy Krueger's house. 
I don’t think I’ve watched a horror movie since I bought Rosemary’s Baby last December. Egad - I didn’t realize I was ignoring that genre! It’s time to get out of the comedy, romance, and drama rut I’ve been stuck in!
Ooh, but after reading your postings I want to watch the Nightmare Encyclopedia first! I won’t though; I don’t want to spoil any surprises.
I’ll watch Nightmare on Elm Street tonight but I have to wait until its dark! I won’t watch the bonus disc until I’ve completed the series.
