‘Supernatural’ season 9 spoilers: Official details on ‘Bloodlines’ spin-off

We want to be excited on the “Supernatural” spin-off “Bloodlines,” but we have a feeling that this is ultimately going to be one of those things that we have to see in order to believe. So much of the success of the original is about Jared Padalecki, Jensen Ackles, and the story of the Winchesters, and the characters are going to have to be compelling right out of the gate here in order to work.

The “Bloodlines” backdoor pilot airs on Tuesday, April 29, and in the synopsis from The CW below, you can get some preliminary details regarding just what sort of story lies ahead:

“Sam (Jared Padalecki) and Dean (Jensen Ackles) investigate a case in Chicago, where they discover that various mafia-esque monster families are, unknown to humans, running the underbelly of Chicago. One is a family of shapeshifters run by Margo Lassiter (guest stars Danielle Savre), whose leadership is thrown into question when her brother David (guest star Nathaniel Buzolic) returns home. The other reigning family in town is made up of werewolves, lead by Julian Duval (guest star Sean Faris). While in Chicago, Sam and Dean meet Ennis (guest star Lucien Laviscount), a man with a personal vendetta against the monsters. The Winchesters warn Ennis about heading into the hunter lifestyle, but Ennis refuses to listen and starts down a dangerous path.”

Ennis is the supposed lead of the new show, but Nathaniel Buzolic is the most-interesting cast member right out of the gate thanks to his following as Kol from “The Vampire Diaries.” This will have more of an ensemble feel, which is good in that the show will not have the pressure of relying on just one or two people. However, at the same time the show will have to struggle with trying to make sure that most of these characters still work, since if half of them are dull, the other half will be dragged down.

As soon as The CW starts handing us previews of this one, we’ll have a little bit of a better idea what to expect.
