The keyword phrase "what can you watch patriots day on" functions as an interrogative nominal clause. In this context, it acts as a noun phrase that represents a query. The grammatical purpose is to solicit information, with the answer being a list of specific platforms, which are themselves nouns (primarily proper nouns).
The film "Patriots Day" is available for viewing across several types of platforms, contingent on current digital distribution rights. It can typically be found on subscription-based streaming services, though the specific service may change over time due to licensing agreements. Additionally, the movie is consistently available for digital rental or purchase through transactional video-on-demand (TVOD) platforms such as Amazon Prime Video, Apple TV, Google Play, and Vudu. For physical media collectors, the film is accessible on Blu-ray and DVD formats.
The practical application of this information requires understanding that streaming availability is fluid.
