In an ideal world, a TV series as enjoyable and immersive as HBO’s Game of Thrones would just run all year round, like EastEnders or anything on Dave. We might get bored of it after a while, but it would at least spare us the now annual meet and greet that is the opening episode of a new series. The problem is simple – even the most committed Thronie will admit that the plethora of similar names and imaginary continents, not to mention thousands of years of pre-history, storylines from previous seasons as well as storylines from the books, can get a little confusing. It turns out that the 10 months we have to wait between series is the perfect amount of time for most people's wizened brains to forget what happened to whom last time round.
