I don't have time to go through every posting about this ep so I don't know if someone else might've said this, but I think that "The Betrayal" should have been the series finale.
The last scene with Jerry and Kramer meeting for the first time and Kramer looking into Jerry's apartment, as if to visualize all of their futures (and our pasts), would have brought the series to an elegant and poignant conclusion, and reminded us of the circular nature of existance--like finding a beginning at the end.
