SEASON 1
Never have I watched a show that was so well written. Ever. I don't want to give away any spoilers, but damn. The way the foreshadowing is done? Brilliant. Leaves you questions that you dismiss as irrelevant, figuring "Hey, it's a TV show. They can't be perfect." And when you reach the big finale? It's perfect. All those little doubts, those inconsistencies that you brushed aside, all tie together perfectly. It's practically orgasmic. And the characters! Oh man, the characters are brilliant. The very foundation of the show is how brilliantly they've designed their characters, how they seem to be real people. You learn to care about them, to love them. The fantastic humour interspersed throughout the show is a plus, too.
