Following The CW's pickups of four new shows, including The Flash and IZombie, the network has passed on the proposed Supernatural spin-off Supernatural: Bloodlines, while cancelling The Carrie Diaries and first-year shows Star-Crossed and The Tomorrow People.

Supernatural: Bloodlines was considered to have a strong chance of getting picked up, giving the nine-season pedigree of the flagship Supernatural series, which was renewed for Season 10 back in February. However, the back-door pilot, which aired as an episode of Supernatural on April 29, was poorly-received by the fans, with an Entertainment Weekly poll showing only one-third of viewers thought it should be given a series order. However, insiders claim The CW is still open to the possibility of a different Supernatural spin-off in the future.

Supernatural: Bloodlines starred Lucien Laviscount as Ennis Roth, a Chicago police officer trainee whose fiancee is killed during a war with various monsters in the Windy City, causing him to become a monster hunter himself.

As for the current shows which will not be moving forward, none of them posted stellar ratings this season. The Carrie Diaries, a prequel to Sex and the City which stars AnnaSophia Robb as Carrie Bradshaw, averaged just 1.1 million viewers per episode. Star-Crossed, which starred Aimee Teegarden and Matt Lanter as a human girl and an alien boy who fall for one another, didn't fare much better, averaging 1.3 million viewers each week, while The Tomorrow People drew in an average of 1.9 million viewers an episode.

The network announced earlier today that The 100, Hart of Dixie and Beauty & the Beast were picked up for additional seasons, joining previously-renewed shows Arrow, Supernatural, Reign and The Originals.
