Does anybody else miss the early seasons' improvisational tone?

Season 6 writing has been spectular so far, don't get me wrong. And I get that the gradual disappearance of this improvisational tone from the voice acting (mainly Rick and Morty's) may be the result of the show getting more professional as seasons pass, but does anybody else miss it? Or just me? Did they completely axe this alongside ending the Interdimensional Cable series?

The show has mostly stayed true to what made it so good in the first place, and it even improved on some, so I'm not saying the show's lost touch or anything close to that. Well, I guess, maybe some touch. Part of what drew me to the show when I first watched it was Roiland's tendency to fumble and improvise on his lines with his characters (Mr. PoopyButthole, Morty, Rick, etc.) and it was hilarious every time because I've never watched anything like it (and also, he made it work). The later seasons have kinda reinforced my sentiment a little bit as I noticed the voice acting in general has gone, idk, squeaky clean? A little too perfect? Is it weird to feel kinda off about perfection? XD

Idk, I might just be complaining too much. I've been enjoying season six so far anyways... but I'm wondering if anyone else shares the same sentiment.
