There're a great variety of cool movies. Some people prefer horrors to dramas, others are keen on detective films.
Detective films are really popular nowadays. People of all ages wach them. I should say that Sherlock's stories are popular as well. Youth can't help watching well-known TV series staring Benedickt Cambertach. Frankly speaking, it's really hard for me to put it down.
However, I adore sci-fi. My favourite film is Avatar. I think that it's a masterpiece. I've never seen such graping film. What's more special affects are amazing.
To sum up all my ideas, everybody chooses films they like.
