Prequels have a huge weakness in that we can anticipate or predict a lot of things based on the original source material. For example, we have all pretty much established that Snow will come back to life/is not dead and that Wolf will not develop any romantic interests, since he ends up together with Snow. We can also pretty much cross off Bluebeard as the killer, since he is not arrested in the comic. (I think someone is trying to frame him, by the way, seeing as the beheading fits too perfectly into his fairy tale. I also think he hired the reporters to investigate who is framing him. He probably has Crane on his side too.)
Anyways, had this been an adaptation or retelling, then the plot could have been even more interesting. For example, we would be genuinely shocked that Snow might actually be dead...etc.
