While the show itself could be a bit scatterbrained in attempting to tackle so many ideas and issues all at once, her ultimate, hilariously ordinary epiphany from all of it is the best end-cap her journey could have asked for.
The show's curiosity and smarts buoy it during times of less credibility, and there's almost a sense of determination radiating out of the episodes. We're doing this. Luckily, they're doing it pretty well.
Confessional art is one (often wonderful) thing, and confessional art made by women is too often torn apart unthinkingly. But a lengthy meditation by a famous person on their own public image is only interesting if that public figure is doing real reflection. Handler, by contrast, is openly dismissive of anyone who challenges her point-of-view. The race episode is the most pernicious example of that: Handler convenes a panel of activists seemingly only to berate them about how they are wrong and she is right about political correctness.
