Even as hokey as the premise is for Who Am I? I find it to be better than Supercop in large part because everyone in the film, including Asians are speaking English. What's ironic is that there are definitely a few of the American actors who have their own voices dubbed by someone else. Furthermore, I find that American Actors that populate Jackie Chan films to be some of the worst actors ever with their mannerisms. Really not sure why they do this. It's bad acting on grade school level. Even with these little issues, I like the movie. It's entertaining. Jackie Chan movies are like pizza. Even when they are bad, it's still good. 

As with all of Chan's movies, the older he gets, the fewer the fight scenes we get per movie and Who Am I is no exception. There's hardly any fighting going on through the bulk of the movie. Just....teasers if you will. He has to save his stuff for the end and this is where the movie finally delivers. The fight that ensues against 2 dudes, is pretty good (but far from his best). Be sure to stick around through the credits again for the Blooper/Outtake Reel. Definitely worth a Rent. Whatever happened to Michelle Ferre? She's not the best actress out there, far from it, but she does have a certain charisma in this one.
