Probably the most talked about and divisive film of the last few weeks, if not the whole year, has been Christopher Nolan's Interstellar. For its fans, it's a bold and ambitious attempt to use blockbuster filmmaking to tell a story of space exploration, love and quantum physics. For its detractors, it's an overblown mess that awkwardly blends mawkish sentimentality with pretensions of intellectualism. Joe and Ed were similarly divided on the film, so they decided to spend a whole episode talking about the film's merits and its flaws, and what they reveal about Nolan's work as a whole.

In honour of the brilliantly named Days of Fear and Wonder season currently being run by the BFI, Joe and Ed spend the latest episode talking about science fiction. They discuss their favourite sci-fi films, how some great ones manage to use big ideas to make up for low budgets, the reasons why the genre as a whole seems to be held in higher esteem by critics than horror, and the role that it can play in representing contemporary fears in fantastical settings. It all ends with a lovely little song as well.

After a bit of a break from the Alternate 100, Joe and Ed return to their pet project with renewed zeal for an episode that is heavy on V subjects. They talk about voyeurism, vampires and Vietnam, but also maintain a light touch by trying to make "fetch" happen, and debate the proper way to pronounce "coven".

This week, the boys are - much like Rodney Dangerfield - going back to school, with an episode that explores the teen experience and the perils of secondary education.
