10 Once-Lovable TV Characters Who Became Completely Repulsive

When this titan of all sitcoms began, Monica Geller was an amiable, responsible, clean freak who possessed all the typical traits of a neglected daughter. Sure, she was a little tightly-wound, but that's what happens when you grow up in the shadow of your older brother, constantly craving attention.

It was easy to feel bad for her because her parents treated her like secondhand garbage.

Partly because of that, she couldn't even hold down a relationship with an expertly-mustachioed Tom Selleck. Monica's boyfriend troubles didn't make her annoying, though. They made her pitiable and empathetic.

Then came Chandler f**king Bing.

From the moment she hooked up with the group's funnyman at her brother's wedding, Monica began a steep downhill slide into her position as the group's most unrelenting shrew. In a post-Richard world, Monica lost nearly all of her redeeming qualities, and those traits which were generously referred to as "quirks" in the past - her obsessive tidiness, unhealthy competitiveness, and general egotism - began to careen out of control.

Every other scene in the later seasons involve Monica trying to control someone else's actions with a domineering beligerence.

Remember that fight Chandler and Monica had right before they moved in together? Where she refused to let him bring pretty much any personal effects into their home? That's a snapshot of their entire relationship.
