ah ok, so, i have to say NO.
While i would not, today, criticize a book just because it's a FRANCHISE NAME book - because hey, maybe it's good? Why would i assume a FRANCHISE NAME book is bad, after all, maybe the writer is a good writer.
But, i would question why one would buy, such a book. FRANCHISE NAME books tend to be some of the worst garbage in existence. Be it a Warhammer 40k book, a Star Wars book, a My Pony Friendship Is Magic book, or really any product of a different medium than [whatever medium the original product was]. The same way that, let's say, FILMS of good books tend to be bad.
