Avoiding the Terran way
When you have the audacity to connect your story to a piece of Trekkian lore as iconic as the Guardian of Forever, the device at the center of "The City on the Edge of Forever," one of the most heralded episodes in the entire canon, you’re probably asking for trouble. You’d better put up or shut up.
They probably should’ve shut up. Or just not used the Guardian of Forever.
I’ll give them this: They tried. They put a character dilemma front and center and played it all the way through. But in the end this is oh-so-earnest, and overplayed, and frankly unearned. But we’ll get there.
