I took a class on Sartre & de Beauvoir with Professor Johnson. I enjoyed it, and I'm actually taking a class taught by him next quarter. Professor Johnson is an engaging lecturer, but make sure to keep your ears open and don't *just* write down what is on the chalkboard.
He approaches existentialism in an analytic way. There are 2 papers, one midterm (35%) and one final (50%). The first one was about 6 pages, while the second was about 10. There are also weekly reading responses due, graded check/no check. Professor Johnson is an honest grader, and he is quite helpful if you approach him with any questions. You definitely have to work hard in this class and attend lecture, since they aren't podcasted. The papers, for me, took a lot of time. I didn't turn in 3 of the weekly reading responses, so that might have hindered me from getting an A. Overall, I highly recommend this class.

This class is challenging but very rewarding. Professor Johnson is extremely clear, even though the subject matter is sometimes unclear because it's a course on Nietzsche. Most of the class is spent studying two of Nietzsche's books and analyzing a few arguments he's making. Grading is based on mandatory weekly reading responses (15%) and two short papers (85%). The prompts can be difficult, but if you show up and take notes you will be prepared. Attend office hours, ask questions, and you'll learn how to read Nietzsche. I only wish he had podcasted the lectures.
