About Harry Potter movies, I can say that after watching some other films, I found these ones easier to understand, and more useful for learning English than other kinds of movies. This was due to the fact that the English spoken in the collection is very clear, so that I was able to recognize all the words I know and also a lot of idioms studied during lessons. Although my level of English is not high enough to understand everything (as you can imagine), I was always able to understand the meaning of sentences. It is a great source to consolidate what you learnt at school.
