You may ask yourself after having seen the first one, how could a sequel be made after that ending? But since these are movies ... well that's how it is possible. The chemistry is still there. And they still collect ... so pay up! Well I reckon you are not one of the people they come to collect. Also if everyone was paying up, there would not be action (over the top as it may seem at times - though the bar brawl at the beginning ... dang! It almost overshadows the rest of the movie).
Of course this time around they add a bit of story. So it's not just collecting money and then onto the next one to keep collecting. There is also a bigger riff between our two main leads. While they had a love/hate relationship that brought us many fine moments in the first one, it evolved and now there also some secrets here ... of course you could question some motives, but being angry for someone lying to you is not really something anyone wouldn't get. Having said that, this is more than a decent sequel, that is par blow by blow to the first one, if you like movies in its style
