It's worth pointing out that these glib comparisons to old shows are just part of the TV-pitch vocabulary, a shorthand for conveying the genre the show belongs to, and shouldn't be taken as a literal indication that the creators intend to copy the specifics of the shows being referenced. For instance, Gene Roddenberry pitched Star Trek
as "Wagon Train
to the stars," because Wagon Train
was a successful television show that had the kind of format and tone he wanted to emulate, and saying that was a quick-and-dirty way of conveying that to the network execs because they'd know what kind of show it had been. But ST was a very, very different show from Wagon Train
So let's try not to be so quick to accuse people of unoriginality based on the pitch shorthands they use.
