It's a sequel to Sha Po Lang with Donnie Yen, Sammo Hung and Wu Jing - at least in name only. The big draw was supposed to be Tony Jaa vs. Wu Jing
but like everything after Tom Yum Goong that Tony has been in it's a bit disappointing. Received a lot of hype in Hong Kong but don't let that fool you... the fights aren't all that exciting.
