I think Professor/Dr. Minturn is everything that you can hope for in a humanities professor. He is incredibly knowledgeable about each era that is covered, and is able to namedrop with the best of them (in a good way! He can quote many many art critics about any piece/artist etc...). I didn't have a particular interest in art entering the class, but I left appreciating it more than I could imagine. He's a pretty young guy, is extremely friendly/approachable, and is a very good lecturer.
Class structure: Minturn lectures for basically the entire class (which was always cut short 5/10 minutes), allowing for small pockets of discussion that weren't usually used very extensively. I don't know if it was my class in particular, but no one save 2 or 3 people really participated regularly. This isn't good news for those who love to hear themselves speak... BUT, when Dr. Minturn speaks (and again, it's for 95% of the class), it's always interesting. It's not a class where you necessarily WANT to speak out and disrupt the flow, because I really think he is that good at describing the topics/pieces/era/artist/etc. at hand, and it's far more helpful to just let the man do his thing.
Like I'm sure most Art Hum classes are, he comes in w/ a flash drive prepared with a powerpoint filled with the art that we're going to discuss for the day. Slide by slide he narrates. Easy as that.
If you end up with this guy, you are very very lucky. I don't think Art Hum. could be that difficult no matter who teaches it, but Minturn definitely makes it the most interesting and painless (and actually enjoyable).
