Just want to comment on Gellar's new show. After three episodes I have to say it feels like the production team and the writers have been working together for years. The plot is coherent, involving several subplots while keeping a consistent focus on the season's overarching story. The acting is really very good, Gellar is certainly not carrying this show as many may assume.
I suppose my favorite aspect is how Ringer is able to create suspense every episode without throwing in random garbage like Lost has become famous for. Every suspenseful moment is integral to the story. It has an answer that is rewarded to the viewer in a timely fashion. The tone is especially consistent. Realism is hard to do when the very premise of your show is a twin protagonist. It is surprising to see Gellar play a character that is more often vulnerable, but she really captures the audience, without relying on previous roles. I didn't think she was so versatile.
The first season will be great. The real test is whether or not the second season can continue the story quality without sacrificing the tone. I haven't researched the writers yet, but they seem to be playing a rather eloquent game of chess. If you like a good story, give this a try.
