TV shows based on movies don't exactly have the best track record, when you stop to think about it. As a kid, I watched loads of kids programs based on classic Disney animated movies that couldn't hold a candle to the feature films they were leaning heavily on (The Emperor's New School is totally a thing that existed at one point in time for reasons no one can fathom) and many others in this genre (such as last year's heavily derided Rush Hour TV show) have similarly failed to gain traction. But no subgenre of storytelling is inherently flawed and you've got still got programs like M*A*S*H that people adore.
