Each episode has a spin about how something or other relates to Quality Assurance, in a fantastical world and the hard-working commitment that it requires. The quality assurance matter is real but they also present a lot of repetitive cases which is also real, but boring to watch.
I didn't think it looked that interesting but the image pulled me in and I regretted it. It wasn't my cup of tea especially since they wrapped everything in the context of an underlying story, which I didn't connect to on any level, as it was not the reason I wanted to start watching the series from the get go.
Your mileage may vary.
