Since he's the head guy for this cluster I'll review him and the class overall. Decker is a very difficult lecturer to follow. He often starts talking about whats on his slide, which usually barely makes sense, and by the time he moves on you're even more confused than before. He also tends to go into painstaking analysis for everything. I usually started off strong taking notes, but about 20 minutes into the lecture I was hopelessly lost. He also seems to think that he has way more power than he does since he's the head guy for this cluster, so he can be super condescending and kind of a douche.
I wouldn't recommend this cluster at all. The material presented in lecture has nothing to do with the papers you write, which are basically all of your grade. All of the lecturers are pretty awful except for Maverick, who is the only one who is remotely interesting. The amount of reading is absurd compared to how little it is discussed in section, but for some reason they test you on it on the winter quarter final by making you identify excerpts from the reading. The description of the cluster is also bogus, because the entire winter quarter the only relevant music is "All Along the Watchtower" because you have to write a paper on it. Then as soon as you turn that in week 7, they give you a new paper due week 10, while you also get a final on everything going back to fall quarter. The way the class is set up makes no sense and makes it very difficult on you. Don't take it, no matter how interesting it sounds.

I had Decker for the 60s Cluster, both 60A and 60B. While he might be a nice person, he's not the most interesting person to listen to when he is lecturing.

I feel like he could have made his portion of the class a lot more interesting than it was, which by the way consisted of the literature and film. He also seemed to expect too much from a class of science majors that was only taking the cluster to get their GEs out of the way -- which I suppose is his right, but he seemed to get frustrated when no one had input to his questions.

His readings were occasionally interesting, but usually boring. The film clips he did show in class however, were pretty interesting. But I was SUPER disappointed when we only say the opening to the Godfather and not the whole thing.

I didn't take his seminar because I heard it was one of the more difficult ones (although I ended up in one that was pretty hard anyway) and simply because I don't think I was really that interested.

I found that while his portion of the course was one of the most interesting to me, he just had a way of talking that I just didn't enjoy listening to -- sorry Decker, it's not you, its me.
