I think in its 4th season, this series has caught its second wind. Back to the modern-day equivalent of Shakesperean multi-layered cross and conflicting allegiances, betrayals, double dealing, love, hate, and (my favorite genre) revenge... with a healthy dollop of violence interspersed. For me, now that CYE has ended its season, SOS is back to being the best show on TV, (and surprisingly not on a premium network either).
Usually after the 2nd or 3rd season of a show, there's writer fatigue; they run out of novel story lines and become more predictable I feared the Irish plot last season was somewhat contrived and essentially an excuse to take a breather. Well, whether there's an infusion of new writers or the time out was rejuvenating, after 3 episodes, SOS is back with a vengeance... and I'm back to a "can't wait til next week's episode" mindset. Well done!
Oh, and Peggy Bundy is looking every bit the GILF this season too.
