Dear Ben,
It's great to hear from you, even if you're busy preparing for your exams! I hope everything is going well. It's nice that you took some time out to go to the cinema with your friends.
To answer your questions:
1. I like many kinds of films, but I especially enjoy science fiction and historical dramas. I find them both very engaging in different ways.
2. I prefer watching films at home. It's more comfortable, I can pause whenever I need to, and I don't have to worry about other people talking or making noises. I can create a perfect environment for my viewing pleasure.
3. If I had a chance to make a film, I would make one about the life of ordinary people in my country in a particular historical period. I find their stories very interesting and inspiring.
I hope this is a satisfactory answer. I am also pretty busy with my studies but I’ll try to get in touch more often. Take care and good luck with your exams!
Best regards,
