Yes. It could be hard work, however most stuff is hard work or takes time. The point is that Cambridge has put out a list of subjects they don't want people to do, and media studies is like at the top of it.
P.S. The thing I don't particularly understand about media studies is that if you wanted to get a job in say film making, then having a art degree would be better. The same with say if you wanted to go into journalism, then you would probably be better doing a English degree, certainly you will have more options like writing for a newspaper e.t.c.
