Soporific evolution

I do not know what it is. Outdated dialogues of Jean Van Hamme, who begins to show its age? The static drawing is as ultra efficient, Philippe Franck and his heroines to face dying fish on the pier? Its secondary characters more accessories, with insipid Silky Song which is characterized only by his sexual appetite devouring or Miss Pennywinkle who ventured increasingly, whose growth reflects more a screenplay gadget heavy enough that a real evolution? Or the lack of emergency and darkness that was aplenty in the first volumes? Can also be a frustration of having to wait at least a year to know the end of the story? I really do not know why, but Largo Winch tired. I probably lost my child's soul with time, but I feel much more to reading "Chassé-Crusader". It's not bad, right. Just no need. Largo Winch is now slowly falling asleep, and that's probably why he's tired.
