Film is a visual masterpiece, and that alone is absolutely worth the trip to the theater (and by all means to an IMAX one, if there's any around you). It's a little too long (20-30 min. less would make it better). Story itself is pretty weak (packed w/ cliches, as usual, and in several senses a simplified rip off of Miyazaki's Princess Mononoke) but that doesn't really matter. The visuals are absolutely worth it.
Visually mind-boggling, as usual. Confusing story, as usual (for those who didn't read the books, like myself, I'd highly recommend reading the Wikipedia Harry Potter articles.) Found the end of the movie somewhat disappointing. Definitely worth watching, though.
