Not many shows can combine comedy, drama, intrigue and action in one show.
Plus every so often you see something that you think "I'd never see that any anywhere else" and there are just so many charecters to get into.
But if i'm honest i just love to analyse it and i think these days i'm more interested in the company quality than the product itself. I love how they can control (for the most part) how you think and how they manage their storylines.
