TV is a good thing that a lot of people find enjoyable. You can watch cool movies, animated ones, TV-shows and anything you like. But at the same time it's not healthy to sit in front of TV all day and all night. There must be a break. You can get bad eyesight. And sitting at one place is not a very good way of living. So if you like watch TV, it's totally cool, you can watch it but not for a long time.
