Don't watch this without having seen the first movie of the trilogy. It is hard to comprehend at times as it is (and has a casino scene that is quite long - too long?) to boost with. Maybe you are into that sort of thing and the first one had a lot of dialog too - a lot of explanation or attempts too. Certain things get revealed here with flashbacks, that we were not aware of.
But as it is, this is the weakest link/entry of them all. That being said and while not just my rating dropped, but also that of the BBFC (from 18 to a 15), this still isn't for children. For those who care and think animation is always kids stuff (it ain't and boy is there a whole world of Japanese Anime, not to mention Hentai for you to discover ... if you are into that sort of stuff of course) - the movie is at least decent with some nice action scenes to carry you through it.
