What I thought it did uniquely well was create a sense of dread around the fairly ordinary setting: this old house -- despite having some very weird markings above its doors and windows and whatnot -- has a fabulous old basement. Having grown up in a house that also had this fabulously creepy basement, I can tell you that -- as a young'un -- I experienced more than my fair share of frights in those deathly hallowed halls. It was the kind of place you never wanted to be caught down in when the lights went out, and it was the stuff of legend for any good number of movies.
The Cellar makes great use of its location. Though I found its ending more than a bit unsatisfying, it's hard to fault those ghostly interiors in any way: much like the haunts of my youth, the one depicted here was easily acceptable as the foyer to a dark underworld awaiting those inhabitants.
From what I know, the film drops onto shelves today for those who prefer picking up physical media (I'm still hooked on it, though I make exceptions from time-to-time); and I'll put a few good links below for interested parties to check out. You know what to do.
