I think my mom believes The Nightmare Before Christmas is my favorite movie.
Why do you not like the Nightmare before Christmas?
I don't know, I just hate it.
We all have different tastes in films and there is nothing wrong with have your own preferences. It is a bummer that your mom assumes "The Nightmare Before Christmas" is your favorite, so perhaps let her know it's not so you won't have to watch it again moving forward.
Yeah, I don't like the movie so I won't watch it. If I don't explain it to her, I'm going to have a problem.
Seems like a respectful conversation about movie choices and preferences is in order. It's understandable that things like this happen sometimes. Kids grow up, tastes change. It's all good.
