While browsing for the DVD of the Charles Bronson/Lee Marvin fugitive fur-trapper classic Death Hunt on Amazon.com, Austin360.com's Dave Thomas discovered a feature he hadn't noticed before*: User submitted plot keyword tags, ranging from the extremely broad (clicking "Snow" brings you to 16 pages of wintry titles, including The Empire Strikes Back and, predictably, White Christmas) to the highly specific ("Shot In The Eye" conveniently aggregates movies, such as Saving Private Ryan and The Godfather, that feature a well-placed bullet in the peeper, though a separate tag exists for "Shot In The Genitals"). The classification system is highly useful, even if it tends to tread into the realm of obsessive excess: V for Vendetta, for example, gets 103 tags, and while it's helpful to remember that Fight Club and The Seven Samurai also feature someone having their head shaved, we think we were fine without having access to a list of titles that also make prominent use of a toilet.

*A reader points out the tags are imported from IMdB.
