Remember how awesome that rock giant scene was in The Hobbit? Well, those giants were taken from the book, and there's a reason that J.R.R. Tolkien felt the need to have "rock" giants instead of just regular giants. That book was published in the 1930s. The point is, just taking a human and making them large hasn't been creatively acceptable in fantasy for a long time. Unfortunately, from the new Jack The Giant Slayer poster, that's what they're sticking with.
So, yeah, Jack the Giant Slayer happens to be one of those movies that I think looks just awful. That's not because I want to hate it, though. I actually really like Bryan Singer as a director, but its for that reason I hold him to the standard of not making movies that look so damn boring. Then again, I always hold out hope that a movie can defy my expectations. I've certainly been proven wrong before.
Jack the Giant Slayer is set for a March 2013 release.
