Finale - No Spoiler
I realize this was filmed before the cancellation was announced so it probably wasn't intended to be a finale. But even as an episode, it sucked.
shareI guess one good thing came out of it. According to this article Mac & Riley were intended to end up together. That would have been weird. She was his best friend's daughter (more or less). Would have been better to reignite the Bozer/Riley match.
