So I have many thoughts
- Over-reliance on CGI to the detriment of having practical effects, making films feel same-y between one another. Especially true when you have kaiju-monster-type stuff or fight between two superhero-brawlers in front of a bluescreen. Not to rag on these two genres, but when your tech allows the camera to spin in any direction you want, I think you lose a sense of grounding. A sense of: "I'm paying attention to this, because someone actually made that thing happen..."
- Just bad writing. I think most comes from the injection of humor, or trying to inject humor, into stories that don't need it. No longer do we get a "Man with a troubled past..." archetype (or rarely, or it's a throw-away line) because everyone's now a joker who lives right down the street and so you can relate.
- I also imagine there are international dynamics at play here. Language translations are easier when you have brief quips between characters, rather than dialogue where certain idioms don't carry over well.
- Remakes that don't need it. I think this goes without saying. The original yet still popular films are (or, tend to be) better. What I would consider doing is finding a previous movie or genre that didn't do well because the technology and effects just weren't there yet, and expanding upon that. Like, the Lord of the Rings had some cruddy animated version in the 1970s that was only liberated by Peter Jackson's vision. You have to be thinking about that.
