Superb cinematography,which is done justice by the Blu-Ray version.
High production values,which are head,and shoulders,above Tony Jaa's previous two films.
A good storyline which is more than one of revenge.
Excelllent direction,by both Tony Jaa,and his replacement.
Sequences,such as the Court dancing,which stick in the mind.
The fight sequences,in the main,appear to be artificially speeded up.
I don't know if Tony Jaa was out of his comfort zone fighting with weapons which necessitated fights being staged more slowly,and thus required subsequent artificial speeding up,but the sequences do look unnatural,especially when compared to the sequence featuring the masked figue performing Muay Thai before the court.
This latter sequence has speed,power,and grace that looks entirely natural.
