"
Lavin did great work on the show but I actually thought the last episode, which heavily featured Pamela Adlon and Richard Kind, was by far the best of the series. Adlon, who will replace Lavin if the show gets picked up for a second season, can more organically be woven into plots with the other three roommates. During the first 8 episodes, it was sometimes a struggle finding reasons for Lavin to hang out with her son's friends, which is less of an issue with a sister figure than a mom figure.
Meanwhile Kind, who is never playing anything other than Richard Kind, is a great comedic foil for Nathan Lane. He probably wouldn't be brought back as a series regular, but the shlubby Jewish guy with no personal boundaries and a one sided infatuation with Lane, I thought was a slightly funnier angle for driving Lane nuts, than yet another overbearing, Jewish mother (not that Lavin's character was a one dimensional stereotype, her befriending a phone scammer was a great subversion).
Matt Bomer was the weakest link on the show for me, at least as written. Rose from Golden Girls is very clearly what they're going with his role, but while Rose was ditsy, she was also the most emotionally intelligent character on Golden Girls. Bomer's character is just stupid, and inconsistently so. He's also not as good of an actor as Betty White, though that's probably a ridiculously high bar.
