Anime itself is... beautiful. I mean, yuri, H fanservice, humor, some guest/crossover characters - all that filler part is whatever, a matter of personal preferences. However, the essence of the anime is beautiful. Elegant. Delicate. A very careful mix of Japan mythology, philosophy questions and tragic characters. Each episode is like a piece of a picture. No need to look on it up close, stand back a little and take a wider perspective. Yes, reverse storytelling is hard to comprehend in general. However, I believe after ~5-6 episodes you will memorize most of important characters/points, and further episodes will be easier to watch. Soundtrack is nice,though felt repetitive sometimes. Visuals are mostly good. Storytelling is potentially the biggest issue for any viewer. If you are not sure about reverse order - can try chronological. If you are past 25-30% of episodes and it does not hook you - that might be the moment to drop.

Despite not playing OG VN, I think watching anime after playing VN will not give you a lot of new information. It is rather that anime advertises VN, not vice versa.
