No need to get rid of anything.
Just be mindful of how you feel when you're watching a show or film. Ask yourself constantly about the quality of the experience and whether or not it's actually making you happy. If not, why not? Reflect on the impermanence of the entertainment, the non-self of the activity, the dukkha inherent in when your favorite show ends, gets cancelled, has a bad season, has an actor or actress die or get written off, etc and so forth. When reflecting on these qualities of existence you will feel appropriately and do what you should do at that time: no need to get the ego involved in forcing yourself to suppress desire for entertainments.
