Honestly, I generally advise people to stick it out and complete their degree when they want to drop out/change, however in your case I don't think it would do you any favours. Gibing this degree up and changing to another would be far more beneficial to you than sticking this one out and getting a third. I would finish the semester, lets face it, it's only a few more weeks, but I'd look into options surrounding film. What makes you say it doesn't fit your personality? No one type of person likes film!
