Does Endgame mark a decisive win for “content” over “cinema”?

Cinema is dead and Endgame killed it. It may sound paradoxical to say that a film that put butts in seats to the tune of $1.2 billion last weekend was the nail in the coffin of the cinema experience, but that’s the argument that film critic Matt Zoller Seitz puts forth in a new essay on RogerEbert.com. What’s more, Seitz argues that the success of Endgame and, to a similar degree, the spectacle of Game Of Thrones’ most recent episode, marks the transition from one era to another. It is, in a broad sense, the end of cinema and the beginning of content.
In this context, Seitz uses the word “content” to signify a piece of media that’s synonymous with a brand and exists as part of a larger content stream, in which one piece blends seamlessly into the next to cross platforms and string the audience along. “Cinema,” on the other hand, refers to a single cinematic work that exists as an end in itself. In the last ten years, we’ve seen a lot more of the former than the later. The films of the MCU, Seitz argues, bear a closer resemblance to serialized television than they do the standalone blockbuster features of old. Alternatively, the Game Of Thrones showrunners are boastful of the fact that this season of their TV show is more akin to six mini-movies.
