Here's the hard-to-swallow pill: ALL movies are stupid. Go back & watch the original Star Wars trilogy as an adult. Slow pacing, among a myriad of other problems. But that doesn't mean that I love Star Wars any less, or Bill & Ted, or Back to the Future!
Movies exist for entertainment. Most are kinda dumb, some are good, and some are really great. For pretty much all of them, you have to put on your 12-year-old-kid hat & just enjoy the movie for what it is. Doing a film analysis on any episode from the Fast & Furious franchise is going to be an exercise in sadness. But, turn off the lights, turn up your subwoofer, and enjoy the show with some snacks and you can have a pretty great time! There's nothing I love more than unplugging at the end of a long day & digging into a great TV series or movie.
There are dumb movies out there. Go & watch "In the Name of the King" if you want a good laugh (at its terrible-ness, lol). Some shows jump the shark, too - like, I'm a big Walking Dead fan, but I'm a couple seasons behind because Negan got so cheesy & the story kind of stalled out. I'm currently enjoying the Orville (Seth McFarlane). I just saw Howl's Movie Castle (special dubbed re-release in theaters with digital projection), which was awesome to see on the big screen. I think two things are important when watching movies:
1. Calibrating your expectations to the movie in question
2. Putting on your kid-hat & turning off the analytical part of your brain
Like, I watched the Rampage movie with the Rock. It's the same as every other Rock movie: Rock gets in trouble, Rock is awesome, Rock fixes the situation. But it was really fun for a popcorn flick! Is it up there with say, Shawshank Redemption? No, but I went in knowing it was a "The Rock" movie & I put on my kid-hat & enjoyed some popcorn. Mission Impossible movies are the same way...some are actually really good (first one was amazing! I had to re-watch it a second time in order to figure it out, haha!), some are pure action movies, but you more or less know what you're getting...Tom Cruise running around at full-tilt, doing crazy stunts, with a time-driven story & a crew of helpers to assist him in getting the job done. If you stop enjoying the sillyness & start analyzing the reality of the show, then your fun factor is going to go waaaaaay down, lol.
It's the same reason why so many people jumped on Sharknado...you KNEW it was going to be really stupid going in, and that's what made it fun. It's like eating fast food...you know exactly what you're getting, and you enjoy it for what it is, lol!
