The better phrase is “forgettable plots.”
Some say there are only 3 basic plots, some 6, some 7, some 9...
The art is in the telling.
That, or maybe we're all just jaded by entertainment overload. Used to be a time when some guy would stand up and tell a story to the rest around the campfire.
I have noticed too many super hero movies. I did not even care for their comic books in the 1950s or 1960s. Same for so many modern “John and Mary must SAVE THE WORLD (OR UNIVERSE)” type movies.
Our sixplex theater was built about 25 years ago. I went one time in 2010 to see the remake True Grit. The rest of the movies have all been silly superhero, SI-FI movies or horror shows.and a kiddie show. It closed a few months ago now we have no local theater.
I don’t even watch modern movies on DirecTV.
I still like the OLD movies with great story lines and plots. Not today’s regurgitated garbage.
We used to go to the theater a few times a month back before 2000.
