First one was good, second was ok, third was good again, but forth was complete garbage. I lost my interest in them. The ''bad guy'' died, the plot twisted itself and almost died and i don't know what the hell is happening there. At the end of 4 movie i thought to myself, 'Who's that dying? Was that the good guy? Why is that guy laughing? Was he the bad guy? Who are they? Why was it so boring?' At the end of the movie i did not know their names and their faces were unfamiliar even when they have been on screen for so long time.
