I saw three of the movies listed. Most of them I don’t have a desire. Argo, Lincoln, and The Avengers are the ones I saw and they were pretty good. From the list, I would say you are not missing much. Keep with your principles and don’t watch another movie....lol. Seriously, I did see Parental Guidance on Christmas with the entire family and was grateful to be able to see a movie with the four kids and wife without cursing and sex.
Your family sounds rather dysfunctional. I'd suggest counseling.
