I think Star Trek
can be lots of things, depending upon how it is handled.
TOS was touted as "Wagon Train to the Stars" but was really more like "Gulliver's Travels in Outer Space."
Just as DS9 kinda became "Casablanca in Outer Space" and VOY was "The Odyssey with a Starship."
That being said, "Robin Hood in Space" has been done by now, rather a lot.
