Hansel & Gretel: Witch Hunters

I’ve watched this movie a few times now. I really want to like it more than I do. It’s got steam punk weaponry, beautiful cast, witches, magic and tons of action scenes. Why does it bore me?! Pretty sure it is the cast. Jeremy Renner sleepwalks his way through the film and he and Gemma Arteton have ZERO chemistry. Actually, NO ONE does, really. Gemma and the troll 'Edward' have more chemistry between them than anyone else in the cast!
