This isn't a "great" game by any means, but its fast-paced, fun, and provides a great cinematic feel.
As either Aragorn, Legolas, or Gimli, you run through about a dozen levels killing the various monsters from the movies (the game spans Fellowship and Two Towers). What separates this from the average lame movie tie-in is how much it feels like the actual movie, from the excellently rendered settings to the musical score. Now that its at a low price, theres no reason not to get it.
