I just mowed through the first four episodes (on DVD) of Showtime’s original series, “Sleeper Cell,” and I have to say, I’m very impressed. It follows an undercover FBI agent (Michael Ealy) as he infiltrates an Al-Qaeda-esque terrorist cell operating in Los Angeles. The antagonist is the cell leader (Oded Fehr) who constantly keeps the undercover agent on his toes as he plans an attack on the city that he calls “Judgment Day.”
It feels like “The Shield” and a more realistic version of “24.” The first season is out on DVD and Showtime is currently showing the second season on consecutive nights.
