From the very first episode - I didn't care about DeSinge.
Monkey Island has always been great about taking characters who are small - who are merely there to entertain, or to even change the direction of the plot - and make you care about them or enjoy them. DeSinge - I didn't like him, and even though he did change the direction of the plot (sending Morgan after Guybrush, causing Guybrush to lose a hand, having Morgan bring him back to Flotsam, taking focus off of the real villain, the final confrontation...) I didn't care about him, and I feel like he is one of the most forgettable characters in MI history. I guess what I am saying is that this is the first MI character that I've encountered who, even though might be important to the plot, I didn't care about. I'm not going to say he is the most unlikable character in the whole series, but he ranks up there.
I understand his role, I get why he is there - I just didn't care about him at all. Every time he was referenced I thought - oh geeze, guess they've got to bring him up again. Didn't like him, didn't care about him - which stinks, because I feel like I care about most MI characters - even the little ones. (I always wished Capt. Smirk would have come back up - MI2 or MI3 or something).
Another point - I feel like this is the first Monkey Island game with really really forgettable characters. anyone else feel that way? All the other games seemed to have great supporting players (even EMI) but this one...most of them are just forgettable. thoughts?
