Abby Elliot is mostly good as one of the extra people in a sketch who has a couple lines but isn't the main focus. She's not good enough to draw attention to herself, but also doesn't do anything bad enough to hurt anything. As opposed to Jenny Slate and Bobby Moynihan, who are occasionally quite funny, but just as often distractingly obnoxious.
Nasim Pedrad is a keeper, though. She's one they can actually build off of.
