Stargate didn't have much of a backstory to it and was successful ..........................
Especially Shatner... In his own universe ENT got canceled because it was nothing like TOS
Stargate has a huge back story, with one movie, two series, two more movies, tons of books and tech manuals. Oh and a new series on the way
Shatner is probably right, like it or not, Enterprise was doing SOMETHING wrong. Getting bogged down in interstellar politics, wrong. DS9 did it well ENT didn't. The first season with actual single ship exploration, that was fun to watch.
Gary Seven might work with a total seperation from star trek. The basic concept is cool, make his big wall safe in his office not only a transporter, but also a time machine. interact with major and minor events. A cross between dr. who and quantium leap.
The academy, school shows only work as dramas.
Or a show that takes place entirely in Quarks bar, kind of like cheers. The bar, casino, holodeck and whatever else the shory needs. First episode Dolphin sex slaves.
