Many people enjoy watching movies in a cinema. They think the cinema has a better atmosphere (气氛) to enjoy the movie. However, I think people are happier and freer when watching movies at home.
Watching movies at home is more comfortable. To watch movies in a cinema, you have to buy a ticket before you go there for a better seat. However, there is no need for people at home to worry about the ticket. They can enjoy movies at any time they like and with the most comfortable seat. What's more, people watching movies at home wouldn't have to face any traffic problems.
It is free to watch movies at home. In the cinema, we can't go outside and do something else because the movie won't wait for us. Sometimes, if we miss part of the movie, we can't follow the story. At home, we can pause at any time and go back to watch the part.
All in all, a cinema is a good place to watch movies, but it isn't the best place to enjoy the movies. I think watching movies at home is better.
