What is good?
-- They managed to secure the rights to film in 3 great historical locations 
i.e., China, at Xi'an's The First Emperor's Terra-Cotta Soldiers and Horses Museum ...
i.e., China, at the waterfall in Yunnan ...
i.e., India, at the 15th-century Virupaksha temple at Hampi ...
-- In terms of editing, the many transitions between the past and the future were rather well choreographed ...
-- Most audience would like these two rather comical scenes 
(i) the scene with Jackie Chan blowing the flute and a cobra sashaying (initially, at the theater, I thought the cobra was a computer generated animal ... but when I watched the "making of" on TV, the cobra was actually real!
(ii) the scene when the cast were fighting on a "conveyor" belt ... kind of funny ... (just very "Jackie Chan")
-- Like most Jackie Chan's film, the "ending" N.G. takes are most fun to watch ...

What could be better?
-- The initial philosophical take about reality versus fantasy and what is past versus what is present degenerate to nothing too soon, such that the film only becomes an action/comedy film ... Aso, I thought Tony Leung (Ka Fai)'s was under utilized by having a comical take on its character ...
-- For the first half of the film, I thougt they were filiming in India because such story often entails the belief of reincarnation (in Buddhism) ... Unfortunately, it took a comic turn and scenes in India were all filmed to be comical ... For the second half of the film, although Chinese do have many myths and beliefs, it just did not look credible ...
-- The good versus evil (i.e., villain) take was not compelling and appeared kind of contrived ...
-- Overall, there was not enough compelling "scenes" to make one feel the forbidden love between the two main protagonists ...

Conclusion:
Can watch, but I am not crazy over it ... the film is very "Jackie Chan" ... audience will have to like his style of humor combined with actions ... while the first half is kind of action/comedy, the second half is rather weak ...
