I enjoyed Hannibal, but it wasn't for everyone. Visually it was an impressive show and Hannibal's artistic take on graphic violence and gore should be interesting when paired with the Punisher.
not only the visuals
but Hannibal also handled its psychology very well which will be good for The Punisher
it also played a lot in that "what is a hero/villain" arena like Daredevil did this season
