There is a trend with that trilogy of Gleeson films but if I shared that with you, I suspect it would be your loss - you'll know when you see it.
This is really a powerful film. I found it's impact more powerful than 12 Years a Slave and the audience seemed to leave both with the same sense. I honestly don't know why there's a suggestion that this is a comedy - it's not although there are a few bits which could be straight out of Father Ted.
I can't help feel that the timing of the release on the run up to Easter was deliberate. Certainly, it gets my recommendation as a 'must see'.
