I got 35 episodes into Fushigi Yuugi before I realized how deeply stupid the heroine is. Mostly it is her fault for being dumb; sometimes the author throws her the Idiot Ball; sometimes the author bends space, time, and plausibility to make the heroine extra-stupid.
I plan to tough it out and watch this stinker to the end. However, unless you’re deeply committed to watching shows about stupid protagonists, don’t waste your time. Learn from my fail.
This is from the same author who gave us Ayashi no Ceres, which was not this bad, and which ended more promptly.
