The sad reality of the film industry is that every great idea is dependent on its box-office performance. A fun, charming, and creative film like Dungeons & Dragons: Honor Among Thieves can't expect a follow-up without an appropriate mass of millions during its theatrical run. In the modern era, three or four weekends decide the fate of every new idea. Paramount didn't like the numbers they saw after Honor Among Thieves hit the screen, but the streaming spinoff may be a missed opportunity that haunts them.
