There should be a differentiation between recurring characters and one offs who only appeared in 1 or 2 episodes.
Recurring: Frank. "Between you and me Elaine, I think I got a foot odor problem"
One off: The doorman. Just those mind games. Bookman was funny, but the shtick was only good for a few minutes of screen time and starts to get old pretty quick.
Thought about finally watching this. I want to watch Curb, but feel I owe it to Larry David to watch Seinfeld first.
When does it start getting good, you know, when does it become Seinfeld?
There are some good stuff in some of the early seasons. Maybe start here....some classics and semi-classics
S2 E2 - The Pony Remark (classic George moment)
S2 E4 - The Phone Message (classic George moments)
S2 E6 - The Statue (I'm about 50/50 on this episode, but funny guest stars)
S2 E7 - The Revenge (first look at Kramer's physical comedy)
S2 E8 - The Heart Attack (funny guest star)
S2 E11 - The Chinese Restaurant (a classic but maybe slow by today's standards. Often referenced in later seasons)
S2 E12 - The Busboy (another 50/50, but funny Elaine stuff and George guilt)
Eary neurotic Geroge can be fun before he turns into asshole George.
(EDIT) Actually forget S2 E2 - I had it mixed up with another episode.
