OK, it's a Harry Potter movie. If you liked the first dozen then you will like this one. Like the Empire Strikes Back, this one is filler leading up to the last movie(s). Yes you get to see Obi-won... err Dundledorf struck down (ok, that was the end of ep.4) and hear "Luke... err Harry, I'm your... umm... Half-blood prince."
More romance than the others and they cut out the major fight scene.
