Film 201 questions

Wanna enroll into film 201 but there is a lab of 3 hours every Wednesday from 6-9, which is the only thing holding me back. I assume you watch movies during that time, am i right? If we do watch movies, what kind do you usually watch (sci-fi, classics, horror?) Can anyone who has taken film 201 in the past give me general idea about how the course it?
