It isn't quality TV- far from it. Also GGL wasn't a "choice," they were the one that thought there was something to be exploited here and tried to do something along the lines of the drama that you see in "Gold Rush," "Ax men," and so and on, but the problem is that those shows deal in fairly simple concepts (finding gold or lumber) which allows for the drama to take center stage.
The history of the Supes, on the other hand, is complicated, with quite a few players, and much better suited for a PBS or NG type documentary. So in that regard, you are right, GGL is a very bad match for this complex subject. They have the wrong mindset.
Trying to pair up, and quickly sum the complex history of the Supes, yet have time for contrived drama, is just backfiring on them. Viewers interested in actual history find the drama distracting, and the viewers who enjoy drama aren't interested in history.
And those who really know the history of the Supes are doubling over in laughter.
