I literally just got through watching this film from beginning to end for the first time in my life.
Subtract one month, and ditto Saw it for the first time, recently. Watched again with the Ebert commentary and watched the second disc's documentary (wow!).
I've now lent it to a friend (a photographer), since I think he'll really appreciate the lighting and photography of the movie.
This was a very successful sight-unseen purchase.
