It's interesting. I only read a bit so far and it is definitely right sometimes, but I think it often misses the point. For example complaining that the magic system doesn't make sense is silly, since the magic is obviously trying to appear the same as in the original books (where it makes much less sense) while creating an impression that there might be some rules behind it and it being unintuitive and opaque is the whole point, since the rules are hard to find, else they would be found long ago.
