Initially (first few seconds) I thought it was a 'fly on the wall' documentary but was soon disabused of this notion and then spent a pleasant half hour wondering how anybody could make something genuinely funny out of something which is, after all, horrific. I came to the possibly erroneous conclusion that you have to be in the armed forces or ex armed forces to appreciate it. Not quite gallows humour but something akin to it.
I found myself wondering if I should, perhaps, be feeling a little guilty.
Has anybody else seen it? Any opinions please?
