Harry Potter and the Half-Blood Prince
Okay, now this is what a fantasy movie should be. Absolutely gorgeous effects & cinematography (a marked improvement from the drab darkness and excessively cool tones of Order of the Phoenix), a script with a bunch of levity (the first and I think only Harry Potter movie that legitimately made me laugh more than once!), and a climax that, sure, is overwrought, but looks cool and seems important in the overall narrative.
