This is a subtle point.
Not all sensory experiences are bad and bring bad outcomes (kamma vipaka).
– Just because one eats a tasty meal does not mean that it is bad. The Buddha accepted such meals from wealthy people.
– What matters is whether one generates greed when eating such a meal.
– In the case of watching a movie, there is a big difference between watching an adult movie with lust and watching an educational/informative movie.
The easiest way to decide is to see what kinds of feelings are associated with a given event. If it involves greed, anger, hate, jealousy, etc. then those will bring bad vipaka.
