To be honest, I did not attend a single lecture nor read any of the chapters assigned in the textbook because they were not useful in getting a good grade or in completing any of the assignments with the exception of one essay requiring you to compare an adapted film to its original written narrative (obviously you had to read the narrative, but it's uploaded on CCLE and not in the textbook). So that said, I would not recommend buying the textbook, it's a waste of money (~$35) and you'll never need it.
There is a (one page) response paper assigned every week corresponding to a movie you have to watch. This takes about 1-3 hours to write depending on if you have an easy TA or not. On average I got 19/20 on the papers.
There is NO midterm or final for this class but there are 3 essays making up 20% of your grade each. The prompts are given ahead of time so you can easily finish them or get started before the deadline. These took me about 6 hours each and I got 85%, 93%, and 100% on them.
In all, I think it's a relatively easy workload since it's the same thing every week and as long as you participate in the section you'll get full points for the discussion. This class isn't stressful at all as long as you stay on top of your deadlines and ask for clarification about assignments in section (TAs and professor have a very quick response time).
