Sports. If you dig Scottie Pippen, Andres Nocioni, Kirk Hinrich, Luol Deng, Ben Gordon or Jessica Alba (thought I'd slip that in there), then you're a buddy (or buddy-ette) for life.
People who are funny, charming, intelligent, interesting, talented, sensitive, caring, thoughtful...and who always seem to conveniently forget their bad points.
I love old songs. Give me Kenny Rogers, Billy Joel, VST and the NeoColours any time. I also really love Broadway tunes. I'm into Avenue Q, the Producers, Les Miserables, Goodnight Girl, Into the Woods and Bye Bye Birdie.
I liked Forrest Gump (Big Tom Hanks fan), Braveheart (big Mel Gibson fan), Gladiator (big Russel Crowe fan...NOT!), Schindler's List (big...movie?), The Matrix Series (semi-big Keanu Reeves fan), The Star Wars series (big sci fi movie fan), The Xmen, Superman and Spiderman series (big comic book fan...except of the Daredevil, Electra and Hulk movies), Gone with the Wind, On the Waterfront, Reservoir Dogs, From Dusk Till Dawn, Little Mermaid, Beauty and the Beast...
Comedy shows like Frasier, Will and Grace, Seinfeld, Everybody Loves Raymond, King of Queens, Malcolm in the Middle, Simpsons, Drawn Together, South Park (!), Still Standing...
Wheel of Time series by Robert jordan (12 and still counting), Stephen King books (love his short story collections like Night Shift)
Superman?
