I liked everything about this movie, the story, casting, acting, direction, everything. Some frames are so beautiful that they look like paintings (think Degas and one frame, Seurat). The casting was perfect and Richardson delivered one of the bravest and best performances I've ever seen. The tension between both pairs of women--it was an amazing way to build suspense. Even if you don't completely understand the relationship between the two sisters, their passion is obvious. What a great find this movie is.
