Help your potential matches find common interests.
Books: I have many. Some of them are very heavy, serious things.
The ones I routinely come back to, however, are written by Terry
Pratchett and Neil Gaiman.
TV: Not really my forte', but I do routinely watch Game of Thrones.
I liked LOST (obviously). The A-Team (and associated 80's action
shows. Life needs more helicopter chases). The Office. Portlandia.
Hell on Wheels. It's Always Sunny in Philadelphia. Ray Mears. Dual
Survival. Arrested Development. The Venture Brothers.
Movies: So many. Film is an under appreciated art form. The core,
however, of my most frequently rewatched collection is made up of
the LOTR trilogy, the Star Wars trilogy (yes, THREE), Indiana
Jones, and things involving Tim Burton.
Music: I'll give anything a shot. If a song has lyrics, they are
important to me. I can't tune out stupidity. I tend to dislike most
rap/hip-hop because of this. Skinny Puppy is what's presently
playing on Spotify. Viking metal is what I play at the gym. (Well,
metal for weights, dubstep for cardio.)
