Hmm, I dunno, I would watch that (preferrably not sober).
Not sure I've ever seen a trailer showcase what is most likely every effective (and expensive) VFX shot in an entire movie. Maybe two and a half minutes of I, Frankenstein is the perfect length to digest it, especially since it really did seem to give away all of its story and interesting visual moments, but I can't bring myself to say I hated that, as idiotic as it undoubtedly all was. Like honestly, why bother even making it a Frankenstein story?
