Another Potter. This was the weakest of all the Harry Potter films, so far.
The movie begins dark enough, and you have that constant feeling of darkness and creep accompanying you throughout the screentime, which can be a good thing, if done right. However, this film in particular, unlike all the other films, lacks a true climax. The two confrontations at the end of the movie only get you halfway excited before they're already over. Cannot be compared with the thrill you had when Harry fought the basilisk in the second movie, or the visually breathtaking Triwizard tournament in the fourth, or even the battle at the Ministry of Magic in the fifth.
Unfortunately, the majority of the film devotes itself to exploring awkward romances between the now young adult protagonists, and a fair bit of weird humour thrown in to lighten the movie up a little - but it all just feels out of place. Even Luna's performance was only memorable in the previous film. The movie also deals a lot about Horace Slughorn; in fact it could have been named "Slughorn's memory" instead of "the Half-blood Prince", or even better: "Harry Potter and the Teenage Drama", if you ask me, as it would have been more suiting, given that the actual focus, namely the Half Blood Prince, gets pushed aside by David Yates, the man who single-handedly robbed the Harry Potter franchise of all its original ingenuity and magic and turned it into a cold yarn.
I've read the book, and enjoyed it far more than this film adaptation. Harry Potter and the Half Blood Prince does have its moments, when the familiar awe of Hogwarts comes back into you, but they are so few and far between that it just feels like a shadow of the earlier films. I have yet to watch both parts of the Deathly Hallows; I hope David Yates will not disappoint me again.
