Considering Parenthood had its last new episode of 2012 last night, this may seem like an inopportune moment to make a passionate plea with you to start watching the criminally underrated NBC drama. After all, the next new episode doesn’t air until Tuesday, January 1, 2013. (Honestly, I can’t think of a better way to ring in the New Year.) On second thought, that gives you almost three weeks to get up to speed on the first three (and a half) seasons of the series. Now in its fourth season, what started off as a touching, if not Hallmark-y spin on the 1989 Steve Martin movie of the same name, Parenthood is the best drama on television you’re not watching.
