The ensemble cast just works. There is Schwimmer (the nerdy-but-nice-Ross, not to mention slightly neurotic [Hiltbrand 1]); Aniston (Rachel, the spoiled rich girl who started of the show by getting her first jolt of reality as the waitress at the local coffee shop), Arquette (compulsively neat, overachieving Monica, the girl you hated in seventh grade), Leblanc (Joey, a self-absorbed [Hiltbrand], hunky aspiring actor), Perry (Chandler, stuck in an office job he hates but refuses to leave, not to mention his snide sense of humor [Hiltbrand]), and Kudrow (Phoebe, a wifty free spirit and perhaps the most original of the characters) (Thomashoff 2).
The show started in 1994, but never on shaky ground. Though it was not everyone's favorite show from the start, as it progressed it drew more and more people in. The first episode had five members (Ross, Monica, Joey, Chandler, and Phoebe) of the sextet drinking coffee in the Central Perk, the local hang out of the group. In runs Rachel in a wedding dress because she just stood her husband-to-be up at the alter because she thought he looked like Mr. Potato Head. .
From the first episode, all of the relationships start being established as the years go on. Monica and Rachel were childhood friends and lost contact after high school. Monica used to be fat, and Rachel had a nose job. Though at first Rachel seemed nothing more than a rich brat who had never worked and lived off her daddy's credit cards, she soon evolves into much more than that. Ross is Monica's brother and has loved Rachel since high school, and only later does Rachel realize this and starts to return the feelings. They start dating in season two, have a horrible breakup in season three, and for the next years their relationship is on again, off again. Joey and Chandler live across the hall. They are addicted to Baywatch and are incompetent in all things food, thus they are always eating at Monica's (who by the way never has a locked door).
