This can be a difficult question as tastes can be so varied. While some don't like Glee, others think it is the best thing out there. Here are my picks for shows to avoid:
Two and a Half Men: I tried to watch this one with Ashton Kutcher and could not sit through it. I am not a big fan of the show to begin with, but it seemed to be the same tired humor retreaded over and over again.
Girls: Self absorbed people are upset when their parents no longer support them financially. This one is supposed to be a comedy but I just didn't get it. It is hard to root for a spoiled rotten character who whines about everything even though she lives on her own and does quite well. Live in a cardboard box for a few weeks and then we'll talk.
I don't know about True Blood these days as well. After last season, I thought I was let down big time after a promising addition to the cast. It was wasted opportunity and they killed the best character (Russel) at the end of the season finale. I hoped Lilith would of showed up but she turned out to be a hallucination. I am now in the process of getting the first few seasons as I heard they are really good.
As far as music goes, I pretty much like everything. I am not a big fan of rap and hip hop, but even they aren't terrible.
I don't go out to theaters like I used to as they are expensive and money is tight. There are some I have watched on cable I would of felt bad about shelling $12 to watch.
