The best facet of the show is how they appeared to be winning, but always ended losing somehow. Look at George getting into the supermodel club, Kramer wrecking Jerry's attempts to befriend a native american, Elaine becoming interim president and then getting audited, George faking being married and then getting busted, Elaine bidding on JFK's golf clubs and having them run over by Kramer and Newman trafficing returnables to Michigan, Jerry getting close to seeing if they're real and having Elaine barge in and spoil it.
The show was very creative, and didn't depend on the canned laughter and predictability so many other sit-coms have. It didn't feel like they were on a Hollywood set because they made good use of stage space and had a variety of "locations" they performed in.
If anything, the show made ordinary viewers feel better about themselves because they see these folks on TV trying to take illegal shortcuts to improve their lives, and failing.
