As a long-time fan of martial arts and Jackie Chan, I'd say this film shows great promise!  Chan is at his best element here and offers something new from his usual cop roles as he also portrays a Qin dynasty general here.  It's a great respite to see him fighting off enemies with a real weapon, a sword, as compared to his usual stunts and improvised weapons like a chair or a bamboo pole.  This is inflicted with the usual Jackie Chan stamp of humor, that makes itself felt on scenes and sometimes at unexpected sequences. Check this out especially if you're a huge Jackie Chan fan like me!
