Circus of Fear is one way to show the circus...
...but what about the other?
Circuses, at least the non-Greek/non-Roman kind, were always meant to dazzle, amaze, to create wonder and awe.
This trope reflects that.
Much like the Non-Ironic Clown is about clowns being depicted as harbingers of joy and laughter, this is when a circus is presented as a wonderful, dazzling thing.
Values Dissonance often plays a huge part in this (most circuses don't hold up against a "modern", analytical view).
If a show aimed at children has a Circus Episode, the circus in question will most likely be this trope.
When a circus is this, but is then corrupted into a Circus of Fear, it's often a case of Tyrant Takes the Helm.
