The first film's world is only deepened in this one, with the network of assassins and their allies going international - ideas of governments for these assassin guilds, the codes, the respect, the byzantine rules and regulations all make the experience so much more fulfilling.
Gone are the simple Russian mafiosos as the second film introduces us to people who - perhaps for the first time - are far, far more powerful than street thugs. Keanu Reeves continues his stellar performance as exactly what you'd expect a man who's taken as many lives as a single army unit.
Fights are choreographed just as good and only get more ridiculous (in a good way) as the film goes on, finding new and creative locations that keep a modern and elegant feel. Personally liked it just a bit less than Chapter 1.
