I have to say that this is perhaps one of the best movies I've ever seen, and by far the best Jackie Chan one. Now, this movie isn't for everyone, but I think most people will enjoy it. Yes, it's extremely cheesy, but that adds to the greatness of it all.
I first saw this as a low qulity fansub, so finding the DVD was very nice. I've never seen the City Hunter anime (or read the manga), but this movie certianly makes me want to! If you get a laugh out of seeing anime-style humor (falling down, giant mallets, etc.) done in REAL LIFE, then you'll love this! The Street Fighter scene is definately the best (and I'll leave it at that so it's not runined for people who have never seen it). Another great scene is the performance of "Gala Gala Happy", which is a cool song IMO.
If you're an anime fan who likes Jackie Chan, then buy this NOW! If you're not an anime fan, but like Jackie Chan, then you will probably enjoy this. And if you're [insert what you are here], you may or may not like it, but I suggest buying it anyway, because there's a better chance that you will like it than not.
