Yes. It can be a good movie to watch as it is based on a true story. Such movies often offer a real - life perspective that can be both educational and engaging.
Well, it depends on your taste. If you like movies that are inspired by real events and deal with complex topics like the opioid crisis (assuming that's what 'Painkiller' is about), then it could be great. It might show the real - life struggles, the impact on individuals and society, which can be eye - opening. However, if you prefer light - hearted comedies or action - packed blockbusters, it may not be your cup of tea.
