This class was an absolute joke and by far the fluffiest/BS class I've EVER taken throughout my entire educational history.
Gregg is a professor that unfortunately does not belong at an institution at Columbia. He has no clue how to deliver a good lecture. His lecture style is just him standing behind the podium and reading off his lengthy notes non-stop... & his visual aid (PowerPoint) barely has any points on it to complement what he is saying. It was thus so easy to not catch what he was saying once you missed a little halfway. You will definitely see tons of people doing their own stuff during the lecture (that is if they even come in the first place). Also, I'd like to point out that sometimes what he is lecturing on feels so forced - e.g. he makes it seem like the majority of the films produced post 9/11 were because of 9/11; how certain films are feminist films even when they really aren't. In other words, I feel that he tried to force drawing observations from the films even when the link between them is really, really weak. Attendance for class is taken occasionally.
This class also had a mandatory discussion session ran by TAs (for undergrads). The discussion session was even worse - there was no agenda for the discussion session other than to discuss about the film watched during most weeks. The discussion session was maybe about 5 minutes legit and the other 55 minutes stretched out BS. It's very common for my classmates to skip the discussion session (even when it is graded - 20%!). I remembered like half skipped the 2nd discussion session. The census among peers is that it is an ABSOLUTELY-A-WASTE-OF-TIME-I-PROMISE-YOU! Never had more meaningless discussion sessions. I'd bet that no one would even attend it if it wasn't graded. Sorry that I'm kinda repeating my point but if what I've said doesn't tell you the quality of the discussion session, I don't know what will. Just hope that you have a good TA to make it bearable.
TL;DR: do NOT take this class unless you want the fluffiest ever possible class with an incompetent but very nice and approachable Professor. I can guarantee you that you won't learn as much (if any at all) as what you think you'll. Blockbuster is not Gregg's speciality. His speciality: LGBT-related. Maybe his LGBT film class/other classes are better taught, idk.
