Although due to a quirk of the BBC's records one episode of this series is still in black and white, the remainder is in colour, and makes a much better impression (the proof that it's only the colour is in the fact that the black and white episode, Room at the Bottom, feels very creaky). The characters were by now better developed than in previous series, and as a result they gel far better and get more laughs. The reality is that Dad's Army is not, except on rare occasions, hilarious. One of those occasions is in The Bullet is not for Firing, where the inquiry scene compares favourably to any farce ever put on. But it has the wonderful charm and gentle, ironical humour of an Ealing comedy. The trick is that the characters are all, at bottom, nice enough in their own way, and although they may be pompous, overbearing, or deceitful, and they certainly make enough mistakes, they usually put things right in the end: see Branded as an example of that spirit at its best. The extras are disappointing: the interviews for Arnold Ridley's feature are OK but they're edited from old broadcasts and offer nothing new: and the photographs are frankly a waste, they look like stills taken literally from the tape. But this is still well worth the money: after all, it's seven hours of gentle amusement and feel-good factor: so on balance it just about gets 5 stars, not 4. Let's hope that the next series won't be quite as long in coming as this one was!
