oh joy, how i enjoy flat villains with stupid motivations -_-
There are a lot of decent/good "villains" (and even some outstanding ones) in the game.
It's just the Big Bad which is... rather underdeveloped, both because he doesn't shine as a character when he appears and also because he has very little screen time in the first place.
He doesn't really play a meaningful role in the story beside being "that Bad Dude who commands the enemy faction".
i hope at least the story ends on a high note, but the lack of consequences after beating the main story line, as some have indicated, is just baffling to me..
The "high note" is arguable. There's no "lack of consequences", though. The consequences of your actions are told to you in the ending sequences (a short playable vignette, few cutscenes and a narrated recap according to what ending you picked).
What people are complaining about is the fact that after the ending credits you can keep wandering in the world without seeing any post-credit change into the world... The truth is that ironically enough CDPR could just address this preventing you from continuing the game after that... And it would probably be the best choice, given some weird expectations about that.
The idea that they should build entirely different world states to allow you an ego-stroking "victory parade" across the map, even if there isn't any meaningful content left in the game, is honestly a bit silly.
