I installed the app "Just Watch" and it has been helpful in finding tv and movies we want. We are more or less "Rotten Tomatoes" fans and that site has all sorts of lists of prize-winning movies. We watched "Young Frankenstein", which Lynn felt was the dumbest movie she had ever seen. Good dumb tickles my funny bone (lightly) so I didn't think it was poor. On some lists, "Lady Bird" is labeled a good movie. We watched it last night.
You probably know I am not a girl and never have been. "Lady Bird" is a teen girl growing up story and a moving and intelligent one. We watched "It Happened One Night", which was at the tops of several lists and it is old (1934) but good and sensible.
We use Roku to watch tv and movies and just about never use broadcast tv. We use Netflix, Amazon, Acorn and PBS. The two of us have favorite movies. Hers are "Strangers in Good Company" and "Enchanted April". Mine are "The Russians Are Coming!" and "In the Spirit", which is somewhat difficult to find but worth it if you don't watch the cleaned up, sanitized version. I know that The Big Sleep and Casablanca and Citizen Kane are considered wonderful. Historically, they may have been pivotal but I recommend our favorites. Much better!
