It is well written and not sure how much ad–libbing Pilkington does but at the end of the day it doesn't really matter as it works. Pilkington is excellent.
An interesting try but it just gets bogged down after a while – maybe the re–enactments, which were okay in themselves, affected the flow. A good soundtrack and work by the makeup department helped.
For the most part, it is good – the re–enactments are well handled and there is an interesting support cast – but the melodrama takes over. A more condensed screenplay would have left less room for the fairy stuff.
Whilst the screenplay wasn't always that convincing its political message was loud and clear. A good performance from the young lead and the shooting locations helped.
