TV what I've been watching

I've watched a lot of TV lately!

Elementary: ( Quick response to S02 E03, not all that spoilery. )

Person of Interest: ( General reactions, spoilery thematically and character-wise but not so much plot-wise )

Once Upon a Time: ( Plot spoilers through S03E03 )

Agents of SHEILD: ( Vague responses, no spoilers. )
