Am I the only one who is sick and tired of watching movies/tv series depicting supernatural or impossible events?

Movies are leaning this way, but lots of television isn't. Try Jack Ryan, Ozark, Better Call Saul, the Mayans MC, Barry, Chernobyl, silicone valley...these are excellent.

Says the guy with the Super Hero screen ID! But, to answer your query, out of the ones you listed I definitely enjoy “The Avengers”. I will watch just about anything MCU releases. I’ve purchased Phase 1, 2 & 3. Waiting for Phase 4 to be released. Goes for DC as well....including the animated films. I love Super Hero movies and I’m a Trekkie.

Any movie based on Clancy’s books except for when the director changed the villains from Arab terrorists to Neo-Nazis in “The Sum Of All Fears”!
“On the DVD commentary track, Clancy introduces himself as the author of the “book the director ignored”.

I'm not a fan of fantasy tv series or movies. Never watched any of the titles movies you named. I like crime series like NCIS or comedies like 30 Rock.

I think the Supernatural/Fantasy and Superhero genre's have been milked to death as well over the past 25 years.

There are plenty of realistic type shows out there, you didn't mention specifically what you like though so it is hard for me to make suggestions.

Chernobyl (the mini series) is quite realistic. Dramatized to a little bit more than really needed sometimes, but obviously not an outlandish fantasy.

I haven't seen it, but Ford v. Ferarri (2019) is also a well reviewed realistic non-fantasy movie.
