I will check out the red riding series.
Some the best British actors in it.
I couldnt get into the movie... stop watching it
Re-watching right now for the 4th time and yeah if you are not us to British speak it could be a bit get through.
There is a lot of hidden detail. The main thing is the corruption of the police force. And how murder cases can be screwed up.
The twist on the Red Riding hood, with a wolf, badger, pig, and owl are the nicknames of the Yorkshire police officers.
The best of the three is 1983, but it you have to watch all of them to understand there is some really twisted shit.
These movies were made for late night TV.
