This week is full of big premieres, major milestones and some Valentine's Day love.
NBC's "Smash" and ABC's "The River" both premiere, and AMC's "The Walking Dead" returns, followed by their new series from Kevin Smith, "Comic Book Men." For Valentine's Day, there are plenty of big guest stars popping up on our favorite comedies. The handsome James Wolk is playing Max's (Adam Pally) ex on "Happy Endings," and Mary Steenburgen joins recurring guest star James Marsden on "30 Rock."
