Lots of special effects here but they can not help float a story with many flaws even with the appearance of one of my favourite actor Donnie Yen. If you're looking for kung fu martial arts by Donnie Yen, look elsewhere. If you're looking for time travel exploration applications look elsewhere as in my opinion the story writer and director have made a mess of in this movie. The logics don't seem to make any connection particular near the end. There are some sweet eastern romance scenes and the actresses did a good job. The sets do look very well designed and the costumes look great, but in the end the entire movie looks like multimedia college/university project. If you're looking for Chinese time traveller flicks, The Iceman Cometh (1989) starring Yuen Biao is still the benchmark.
