Same here. Honestly the first close to 10 seasons were amazing, but I think they started to run out of really great comedians, and like you mentioned the spontaneity that made it so amazing when it was new started to cannibalize itself with new contestants playing things up to match a comedy formula.
I guess all comedians try to be funny, but the latest series struck me as much less genuine and fun.
TNG and DS9 are my go to comfort watch! Voyager wasn’t too bad either. Stay away from the TNG movies though, unless you just wanna laugh.
