I'm currently studying film at UEL, and I can honestly say that the lectures and the lecturers themselves are amazing. The lecturers are always there on time and are extremely passionate and knowledgeable about film, and if your interested in all aspects of film then I really recommend studying film here. As for the uni itself, I personally think it's great, I couldn't have chosen a better university to go to (but that's based on my own personal experience of course, but many people here are very happy). There are many opportunities here, such as joining clubs and societies, and it's a very diverse university, people have come here from so many different countries and backgrounds. Also, there are many young people here, and older students as well, but I would say that there are more younger students here, so don't think that it's just a uni for mature students. Also living in London is amazing. If you get bored on campus you can just head into London for the day, and having a train station on campus is extremely convenient. There are also supermarkets and other shops in walking distance, and the SU bar and library are great too. And if you're into sports, then I recommend checking out the sports facilities and sports teams here as they are amazing.
All in all, I think you should definitely keep UEL as your first choice, especially as studying film in London could offer some great opertunities compared to universities in other places.
