...But good on its own.
I gotta say, it's kind of like a mix between the first two books of The Prydain Chronicles, just with a ton of characters taken out (some of which I didn't care too much for). They did a good job keeping the characters true to their personalities for once, though their histories had a bit more depth, like Ffludder Fflam's for example.
My favorite character is most definitely Gurgi. Holy smoke, he is adorable XD ! He's just like he is in the books X3 . He has so much potential for a fanfic...which would be a 'flashback' thing, an insight to where he came from, since he is the only one of his 'kind' that there is.
*can't think of much else*
