Well it's my favourite type of film, and it's so good even people who don't like quaint British comedies like it!
This is a prime example of Ealing Studios' success in showing the character and spirit of the British people, on this occasion the focus is on the Scots during war time. It might be argued that the Scottish people here are caricatures, but given the fact that director Mackendrick, writer Mackenzie, and the majority of the cast are also Scots this is more defensible, after all, we can't get in trouble for laughing at ourselves, can we?
The substantial amount of location work done on the Isle Of Barra shows the beauty of the land, and the skill of the director and cameramen. The script is tight (sorry!), witty, and with just enough pathos. The character of Captain Waggett is surely the prototype for Captain Mainwaring in Dad's Army, and if you look closer, other influences become apparent too.
If only all films were made this way...
