Oktober isn't for everyone but if you like this kind of offbeat, twilight-zoney drama the chances are that you'll like it a lot. Tompkinson is a revelation and gives the performance of his career to date. Producers keep casting him in comedies but this proves that his true strength is as a dark and haunted leading man. Id have liked some clearer explanation of how the drug is supposed to work but other than that I think its best the way we are shown what's happening and allowed to figure it out for ourselves. The merry-go-round with the dead Russians on it ranks with the scariest things I've ever seen in a TV drama. Deserves to take its place amongst the classics of British cult TV.
