Well, yeah. But it's not like you can see that it's people he's eating.
Do you think Supernatural is gory? In Hannibal the gory stuff is that they show dead people in a kind of twisted way (not always though).
But couldn't you just watch the first episode at least? iirc the first ep is not that gory.

The word gory sounds really weird now.

I don't mean to force you to watch it, it's just that it's so good!
