The most recent episode shook things up a bit. The second episode was a little slow-paced with not much happening until the very end. However, with the survivors slowly turning, it is becoming increasingly more interesting. The "Buffalo Bill" moment with Bolivar was very eerie and effective, for example.
Plus, we're now getting into actual vampire territory, so I suspect it'll only get more interesting from here.
I'm a big fan of the book (although I never read the other two) and it took a little while for things to pick up in the novel. I'm suspecting the same is the case here. I wonder if they are stretching out the first book for the entire first season or if they plan on adding things or taking elements from the second book, The Fall. Guillermo del Toro said he envisions a three-five season run for the show, which means stretching out the three books for possibly five seasons. I wonder how that'll work. Comparatively speaking, Bryan Fuller is taking a different approach with his TV show incarnation of Hannibal, often times combining books and not adapting them in chronological order (for example: Season 3 is supposed to mash Hannibal Rising with the book Hannibal; Francis Dolarhyde is then supposed to make an appearance toward the end of the third season, hinting at the Red Dragon storyline). Will del Toro, Chuck Hogan and Carlton Cruse adapt the books in chronological order? Will they add plot elements in order to stretch them out to fit a full season? It'll be interesting to see how things evolve from the first season (pending the show gets renewed for a second season, which probably seems likely).
Regardless, I'm still invested in the show. I really like Cory Stroll as Dr. Goodweather and while the show can be a bit corny/cheesy at times, it is refreshing to see del Toro's horrific take on vampires in this most recent age of cutsy and lovelorn vampires.
