At least George, Kramer, and Elaine were unique characters created by their actors. I mean who can't remember Elaine dancing, or George eating an eclair out of the grbage, or Kramer sliding through the door slapping down cash on Jerry's counter and saying "I'm out!". Remember anything Rachel ever did?
NO argument...I was simply pointing out that Aniston is here today gone tomorrow (like Seinfeld)...unless Brad sticks by her.
