I think a big part of the difference we see in TWOK is it's a movie and not a show. When Star Trek got forced into the movie world they lost the ability to a lot of things you can do with a show.
So you have a really interesting premise and really want to make it a show but can't quite get all of the problems out of it and it's mess, you've got another episode next week and the world isn't over.
You make a movie like that... The world may very well be over.
Imagine if Star Trek got some kind of green light to make a feature and they used The Alternative Factor?
So they needed to make good movies that unfortunately lost a lot of what made Star Trek Star Trek.
In 6 movies, how many new worlds did we see? How many new civilizations?
And 2, 3, 4 really were a self absorbed little trilogy that started somewhat ok with TWOK, not an exploration but it was something a Starship would certainly be expected to do, stop a rogue Starship, but then it's the "let's resurrect Spock show" next movie and then the "let's get the gang back and in the clear with a lot of silliness" 4 is one in particular a good "movie" but it's terrible Star Trek. No where near as bad as Insurrection but
And 4 or 5 or all 6 (depending on how you define the expression) have a "bad guy". There were plenty of good antagonists in Star Trek episodes but many had none, just circumstances resulting from exploring new things and leading into action that wasn't necessarily "action" in the movie sense of the word. It's very arguable if the whale turd/dingleberry and V'ger were bad guys, I think the turd does, but only because of it's callous disregard for sentient/sapient life as it turds across the galaxy and almost destroys Terra because it didn't get the hear the end of the last episode of "Single Femaie Whale Lawyer".
