I know Brian is the most hated character in Family Guy but I don't think Lois is much better than him. In fact, I don't think many people even like her at all. When the show started she was the voice-of-reason alongside Brian and was very doting to the family even to Meg (didn't stand out too much but wasn't a bad character either) but as the show was revived, her character quickly deteriorated. Now on her best day she's the standard nagging housewife but at her worst, she's a spiteful jerk and hypocritical slut. I wouldn't even mind this so much if the show didn't always try to paint her in the right no matter what but it does. For example, she's cheated on Peter multiple times and the show always justified even when she almost had sex with Meg's boyfriend. She even "killed" Chris' girlfriend just because they have a better relationship than she and Peter yet the show somehow wanted to believe she was "right" to do that. Worst of all she's rarely ever funny. Terrible people being terrible people is cheap, lazy comedy.
