No spoilers - though I do make reference to characters and known parts of the story (book and film) being present and absent, without going into the details.

In many respects it is complete, albeit a little unresolved at the end. Such a pity it doesn't however go into other aspects of the complete story. We get Red Dragon and Hannibal feature heavily, without Clarice Starling however, and sadly no retelling of the Silence of the Lambs. It begins prior to Red Dragon, to further explain Hannibal Lecter's working relationship with the police, manipulation, and so on, while also working in some of the Mason Verger back story into those parts, making the Hannibal book story work, but for some reason or other they seemed unable to include Clarice Starling and Silence of the Lambs. There was some talk of progress forthcoming in that regard, but it all seems to have now been dropped entirely. As such, you could just watch this, and then when it finishes go into The Silence of the Lambs movie, and have it all end right there. You probably wouldn't want to go into the Hannibal movie however, quite simply because elements of that story pop up in the series.

I've given it 8 stars rather than 10 because it wasn't able to fully embrace all parts of the overall story. I suppose there were some issues with rights, and all that, though I'm not really sure - can only assume.
