What movies make you uncomfortable when you watch it with your family?

My family isnt the uptight sort, we watch war movies and gory horror movies, but we cant watch movies like american pie or fast times at ridgemont high. I been wanting to take my dad and older sister to the movie tropic thunder, but are there alot of jokes, and scenes? i also plan to take my mom and younger sisters to Mama mia, which we all saw the origanl play in Las vegas. are there alot of things in there that are umcomfortable to watch?
