It's a hard question to answer in view of how encompassing it is, but I would say that I do.

It depends on what criteria you use to rate: if enjoyment is an important criterion then give a lower rating (or vice versa). I've thought the same about other shows. I haven't watched Eizouken but have watched Shirobako. And I didn't care for the anime production aspects either, though I liked the lead characters and their development.
