Great stuff. Not a mere slasher, so many interesting levels to the Freddy movies (except Nightmare 2, which is just a slasher). Playing around in the sleep/wake worlds, the sequels playing on the characters' weaknesses instead of their fears, a boogie-man with good backstory. A self-funded, low budget thriller that became a big franchise.
