For me it's theatre or music. Music for conveying some emotional feeling or getting some catharsis in general, though theatre can do that infinitely better since it puts a face on people to make you feel for them. Though music can pull at emotional strings in a way very little else can.
I went ahead and voted Theatre, though, since having been an actor in my school's One Act Play competition--even though a secondary character with a relatively small role--it can be extremely demanding on many levels. Physically, emotionally, vocally (especially if there's singing at any point), and so on. It's extremely difficult for someone to get on stage and truly be another person, and it's harder again for them to ue that person to convey some emotion or some idea. But above all else, when it's done well, it's hard to compare. Film/TV tend to force emotions on you with closeups/extreme closeups, and it can be overwhelming and at times exaggerated to the point that it doesn't feel like normal emotion to me any more. Half of TV/movie emotions aren't real emotions. Granted, theatre can be done that way too, but my experience has tended towards "real emotions and real reactions, just bigger". Everything has to be bigger because if you can't see it from 50 feet away, it does not exist.
tl;dr: theatre because it's harder than most others to do well and by putting you in front of real people being emotional rather than putting a screen between you and them, it makes it seem much more real.
