Everything Going For It....
Great actors and Director, beautiful locations, early electronics, cricket played by crazy people, Progressive Rock soundtrack and reasonably big budget (I'd imagine for the day) this should be seen by more people. It's just so very strange, as if Don't Look Now, The Last Wave, Straw Dogs and The Wicker Man have been put through a blender..!
Having said that, I've been watching films for the best part of 35 years and it's new to me. However, following Hurt's death and a friend recommending it, a quick Google search says it is available here. Not sure how long for though, but it is of good quality..
