There are benevolent dictatorships, Stalinist dictatorships and guys who just want to make their vision happen. I've been in all 3 (and a few more). Obviously don't touch band leaders who are crooks and psycho's with a barge pole, but there is no reason why, if you get the trade off's between the pros and cons right, some of the "difficult" people can't be the most rewarding to work with.
