Weird, very weird. First, I should note that although I hear a lot about Hannibal Lecter, I never read or saw any story on him, and therefore, I was kind of lost. After a quick visit to wikipedia things got clearer. This probably shows that the first episode is not that good as it might be, as people new to the Lecter story might end watching the episode, and be kind of lost.
Nevertheless, I am interested to see next episodes, even with the “viewer discretion advised” message.
