Radio Times review

If you've ever wondered why there's such percolating ill feeling between Mainwaring and Wilson, it's all here in an eye-opening first act. The captain turns puce and looks set to explode ("Judas!") when he learns that his supercilious subordinate is going up in the world, as both bank manager and second lieutenant in neighbouring Eastgate. All the petty jealousy and class resentment come pouring out, and Mainwaring's knee-jerk response is an office/platoon reshuffle.

It's brilliantly acted, but if that sounds a bit intense and uncomfortable, don't worry. There's some fruity role-playing as members of the platoon get ideas above their station and a sizeable innuendo from the Vicar. But the episode is owned by Wilson, and John Le Mesurier. You'll find it hard to swallow after the very last scene.
