With a solid presence at San Diego Comic Con International and a comic book adaptation at Dynamite Entertainment, it’s safe to say that NBC’s Grimm has found a following in the comics community.Apparently, it’s got enough mainstream traction to justify at least one more year, too, as the network today announced that the show will return for a fourth season beginning in the fall.The network also renewed Chicago P.D. and Chicago Fire from Law and Order veteran Dick Wolf and, according to Deadline, looks close to ready to renew the midseason replacement About a Boy, based on Nick Hornby’s novel of the same name.
