We’ve been following Adam Green’s work since Fantastic Fest in 2006. He’s been deliriously prolific ever since, directing three more features over the following four years, as well as a slew of short films. With “Hatchet II,” Green returns to the mythology that started it all. It’s a great horror film, and not for the squeamish. In fact, when “Hatchet II” was released theatrically, it caused a bit of an uproar over its violent content. If you are fascinated by horror films you will want to dive head first into the world of “Hatchet” and the mind of Adam Green.
