Theatre or DVD (Kenny)

There were many people talking about watching a movie in the theatre or watching a DVD at home? For me, I'd like went to theatre for watching a movie, especially action movies. Because I thought watching a movie in the theatre the visual effect were better than wathcing a DVD at home. At home your audio were smaller, and the screen was smaller too. Imagine, when you look at war movies, in the theatre you will feel like in that environment actually, however, if you watching DVD at home you will not feel like this. Someone said that watching a movie in the theatre was very expensive, therefore, I have done some research in the Bestbuy. The new DVD's price were between 10 to 20 dollar, the used DVD's price were cheaper just 5 dollar, but that all the old movies. So as the result, the price between watching a movie in the theatre and watching a DVD at home were same. However, there two reasons I thought watching a DVD at home was better than in the theatre, first,if you really like the movie you can watching it again and again. Second, when the movie was released in the theatre but you didn't had time to went to cinema, and when you had time the movie was finished you could bought DVD. There are some my own opinions do you agree with me ?
