Honestly...
ZZZZZZZZZZZZZ...
Second half really brought the goods.
It also seems like Sharlto Copley is having a great time, so that's cool.
When you watch a young child's homemade, no-budget film, it's usually amusing and charming. They'll probably try their best to wear many different costumes, use disguised voices or impressions, and film in different rooms and various outdoor areas. Maybe the plot is almost non-existent, the editing may be questionable, or the sound quality is ass, but that can be overlooked because they had a lot of fun making it. This fun can radiate through the screen by means of factors…
The movie does suffer some questionable editing during non-action scenes, as well as clunky dialogue and general cheesiness.
However, it more than makes up for it with astounding fight choreography and Tony Jaa's impressive chops. The parkour influenced martial arts are also quite interesting.
