I'm pretty sure a lot of us have experienced this at least once in our life while going to see a movie at the movie theater, There's someone sitting next to you or behind you that is just so rude and obnoxious that it almost ruins the whole experience. For me it happened when I was seeing The Force Awakens for a second time, there was this guy who never stopped laughing at stuff in the film, even at stuff that wasn't really meant to be funny like the references to the old movies and non comedic deaths. He also checked his phone constantly even though he's supposed to leave it off during the movie. Luckily for some reason he left a little over half way in the film and than never came back which saved the rest of the experience for me. I'm sure there are stories like this that are a lot worse than mine so let's see how your bad experiance went.
