You can just tell the humor is not what it used to be after Larry David's departure following Season 7. The jokes are just expected to be funny because of who says them, not because they are clever and unique and never before said on television.
Putting that aside, this was still an excellent episode of TV. The Kramer scenes were legendary and even though this is so exaggerated and unrealistic, you can think of something to relate this to in your life. That is why Seinfeld will always be the number one show.
Good episode, unfortunately it set the bar too high.
