I can remember going to see Batman Forever as a kid and sitting a few rows behind some woman with poofy hair that blocked my view. I had to lean to my right the whole movie to see the screen.
One potentially bad moviegoing experience that I ended up avoiding was when the 50 Shades movie was due to release. I ranted on Facebook that the movie would be trash because it was based on a trash book that started life as a Twilight fanfic and was about a highly toxic relationship between the two characters. A female facebook friend thought my rant was hilarious and wanted to drag me to the theater to watch it with her so we could riff on it and enrage the middle aged housewives and teenage girls who wanted to watch it for wank material. I told her to get me shit-faced drunk first and she agreed. We ended up not going because the movie came out later than expected and I was already back in school in another city.
