I dislike and so don't watch: sport (mindnumbingly boring), talk shows (boring), reality shows (pointless), game shows (most are mindless trivia) and just about any show with the word "celebrity" in the title.
I don't watch live TV because I don't want to have to sit through 5 minutes of commercials every 10 minutes.
I generally like documentaries, but often have issues with the special effects. If the documentary has a lot of flashing / fast-changing scenes, sound effects or loud background music, I can't watch it. When it suddenly speeds up, or slows down. I just want to see things how they are. If the subject matter is interesting, that will keep me engaged and I don't need any special affects added to keep my attention or to make it more 'exciting'.
Edit: also I dislike documentaries that are dummed down, or one that are so obviously staged without it being made clear that this is the case, that seems fake to me.
News and current affairs shows: will watch, because I want to know what is happening in the world, but I'm aware that there are always two or more sides to a news story and I don't like the way music is sometimes added to make it more dramatic, or how new topics are often sensationalised. Most news stories aren't fake as such - they are about real things that are happening, but they are often told with a particular slant, bias or angle, that may or may not support or promote political agendas. I don't like to be told what to think, or how to feel, I just want the facts and all sides of the story so I can make up my own mind about the issue.
