Asking someone why they like something is pointless. Liking and hating something especially in the entertainment area is irrational to begin with as it's entirely based off emotion, which is irrational. Try to explain your favorite food for example and see how hard it is to start describing it in a rational manner. In the end it comes down to "I like it". If it's a question you had to ask then there will be no answer that'll satisfy you.
