...Yeah it's good, but the best show on TV right now? Maybe, not a lot of competition right now.
Actually, I'd argue we're in a historically noteworthy era of high-quality television. The cable networks, particularly HBO and Showtime but also AMC and others, have enabled and even encouraged intelligent, serious (or funny) and above all challenging
I know it's long been considered a truism to say "Everyone knows there's nothing but shit on TV," and I've been anti-television for a good portion of my life... but I feel that lately it's a thriving entertainment medium.
On HBO alone, there's True Detective, Boardwalk Empire, Game of Thrones (not to mention Californication, Girls and others). Can anyone name a time in history when a single network or channel had three shows as compelling as these, all at the same time? It's not just HBO. Homeland is amazing, and American Horror Story, and Hannibal, and on and on. I was a TV-hater from my late teens until roughly the time of Sopranos, but I'm convinced things have really changed. Some great writers and directors are moving to TV from film, instead of vice versa.
