Yeah, it's not a practical film-making course. It's like the difference between creative writing and English Lit. Film at many unis is like the former, at Warwick it's like the latter. It mainly consists of studying the films in terms of film theory. You will learn about films from a historical, artistic, national, techincal persepctive (to a degree, not how a camera works or anything like that, but things like camerawork in the film and how it effects the film as a whole, same for editing, mise en scene etc etc).
Basically, it's just like English lit, just substitute full stops and commas for editing, narrative style for mise en scene etc.
I would say if you don't like english lit then don't do it! If you do, do, and mayb think about the Film and Literature degree rather than the straight film studies course.
