Nice premise and nifty execution. I know to most tv and film buffs this justifies everything. Reminded me of a lesser comedy like 'Friends'.
The characters were far more broader than usual, scenarios more over the top and laughs tad crueler rather than the regular schadenfreude. It's typical season 9. 4 episodes at least dont cut the mustard. Elaine giving up secrets due to alcohol was never mentioned once in 8 series, but suddenly a verbose lush.
Maybe I'm judging harshly due to the greatness of Seinfeld.
