I'm reluctant to watch prison films, especially if they are 'realistic'.
It is interesting to note that some countries with unimaginably horrendous prison conditions are able to come up with stories that are worth 'getting some on you'.
This doesn't go as badly as others in terms of depredations.
Do you like romantic films without the hyperglycemia factor?
Here y'go.
Filmed at the actual prison with inmates making up the supporting cast, the style is 'docu-fiction'.
