If your new blu ray package comes with a family tree featuring more than 60 characters, you know you're in for a complicated viewing experience.
Game of Thrones, an epic HBO production based on George RR Martin's hit series of fantasy novels, is already into its second season in America, and is screening here Sky's Soho channel about a week behind.
If you haven't seen season one yet, it's worth getting hold of the blu ray package and devoting a weekend to watching all 10 episodes.
That's because Game of Thrones plays out like an extended movie, with its lush sets, various plot arcs and devious characters (Peter Dinklage's Tyrion Lannister is a scene-stealer) competing for attention.
This is not a show made for ad breaks or week-long gaps between episodes, and needless to say, there's nothing else like on TV.
