But all the same, Hannibal is one of those shows that people constantly worry might be cancelled due to ratings, despite all the positive reviews from critics. Bryan Fuller is also one of those creators who has made some amazing shows that have unfortunately been short lived, so people keep rooting for Hannibal to do well and get renewed. It's also why people are hoping that the move from fall to summer will be good for it overall.
