My eyes are bulging out of my head this morning. I’m suffering from an overdose of Homeland. The riveting Showtime series is a favorite of mine and I usually wait until the season ends before disks are available from Netflix. Last night, however, I stumbled onto the OnDemand menu while looking for movies and lo and behold, it was “Free Showtime Weekend.” Taking in Carrie’s and Saul’s adventures in one day is not for the faint of heart, but by 9 p.m., I watched the season finale with three hours to go before Showtime again disappeared into the ether. Whew.
