SEASON FINALE: Christine Baranski is gone from The Good Wife, now that that series has ended on CBS, but she’s not through with the network quite yet. Tonight she returns, yet again, as Leonard’s tightly wound, highly critical mother, in a Big Bang Theory season finale that also makes room for other Emmy-winning guest stars portraying parents. Laurie Metcalf makes another appearance as Sheldon’s religious mom, and Judd Hirsch makes his first appearance – but most probably not his last – as Leonard’s father. Sheldon’s parents have just divorced, and descend upon their son with points to make, settles to score, and old wounds to probe. Just in time for Leonard and Penny’s post-wedding “ceremony.”
