Um Agente Fora de Série

Actually quite the forgettable character here. But it's an illness he has - which does not make him a good witness. To anything - much less a crime he saw. Having said all that, since it is Sammo Hung you can bet there is a lot of fighting going on - emphasized with some CGI (the impact of the things Hungs character is doing).

And while there are some fights throughout, the ending felt or reminded me a little bit of the movie Unforgiven ... the old man who has to deal with a lot of bad guys. Hung having dementia ... he does not use the tools we've seen in something like Memento - just in case you though that. Add to that a side story with Andy Lau ... also quite action packed when he has the chance and certainly one of the best stunt set pieces set in a staircase ... and you have quite the entertaining movie, that also is giving you a story to have fun with (though fun may be the wrong choice of word ... since it's more a drama)
