Gillian Anderson (“The X-Files”) has a memorable, if over-the-top, role as Sugar's madam. Grant is intensely creepy as the demented doctor. O'Dowd, in places, brings some humor to the relentlessly bleak affair, but the performance of Garai is the most intriguing of all. The range shown as Sugar is a tremendous portrait, which ultimately makes ‘Crimson' truly captivating in its portrayal of desperate times.
Extras on the DVD set include deleted scenes, character biographies, and interviews.
