Liz the bartender
This writing after this character appeared was not so great.
Even Dakota a passing hookup is more likable than her. Liz was cool at the beginning but became just a judgmental character calling Will's relationship with his neighbors weird all the time. The way she called Fiona psychotic was just mean and she was so immature saying that Will chose his neighbors over her.I know the Fiona and Marcus are supposed to be viewed as weird but having close neighbors used to be the norm in society.
Anyway apart from my subjective dislike of one character, I just hate how the writing pushes the characters out of character. Fiona and Will fighting after the breakup with Liz just did not fit. Will and Marcus have gone through a lot so Fiona's weirdness getting into the way of a date with one woman was just not cause for Will to say that he wishes his neighbors to be out of his life. Just too out of character and stupid.
