I don't know how I feel about it quite yet, to be completely honest. The Host is actually one of my favorite novels and... so far what I'm seeing is not on par with how I see the book in my head. As amazing as this cast is (ugh so in love with Max Irons) I really think they got it wrong. That's not to say my opinion won't change come next year but so far, I'm not liking what I see.
The teaser trailer was also released today. See below.
