First time I've come across this. Thank you.
I poked around a bit on the site. The titles combined with the descriptions make it all sound heavily formulaic. As you said this can make it repetitive. Still, formulaic is not in of itself a bad thing. It's all in how you make use of the forms. An additional challenge is that they are all obviously non-English works. Even the best of a series can be FUBAR through an indifferent translator.
If you have any recommendations for a completed series I'd like to know. Preferably something not too long as I have other outstanding commitments to read and review.
Otherwise I'll tool around a bit with it and see if I can stumble on something good.
