I saw this last night. If you didn't like Red Dragon or Hannibal, you probably won't like this. I took it as a story by itself and enjoyed it well enough. My wife thought the lead actor was sexy, if that helps anyone make a decision whether or not to see it.
June and July will be excellent for me as a WHO fan, because, of course, as JALman mentioned, we get series three on Sci-Fi in July, but also, for us Colorado Whovians, Rocky Mountain PBS will begin airing the Eccleston episodes in June!
