I'm not sure what to think of the series finale, as Kramer stated in the beginning of the bookstore "I don't get it, am I right people?"
Everything builds up nicely until the plane starts to come down, after that it seems all anti-climatic to me, it's not like i hate the episode but I feel something is missing, perhaps all that footage that they had to cut down because of time constraints, one day I would love to see all of it, maybe in the DVD
I do like how it all comes full circle in the end, with the same conversation that started the show 9 years earlier, anyways if that was how Larry saw closure on the show I have to respect it.
