As you’ve probably noticed, TV critics spend a lot of their time trying to identify which other programmes the one they’re reviewing most resembles. Sadly, in the case of BBC2’s The Entire Universe, this noble quest proved futile. Written and emceed by Eric Idle, the show did contain plenty of familiar television elements: songs, dance troupes, Warwick Davis making jokes about how small he is, a lecture by Professor Brian Cox on the nature of the cosmos.
