Okay, I just saw Howl's Moving Castle (saw Batman Begins too and made a whole Christian Bale weekend out of it ) and LOVED IT.
As to be expected of Miyazaki, the film was visually stunning. Just swept me away into the dream world, and I loved every minute of it. I also liked the dub, and kudos for getting some British and aged actors. I loved Lauren Bacall as the Witch of the Waste. And for Miyazaki's first real "romance" I really liked the dynamic between Howl and Sophie. And woot for the first kissing scene in a Miyzaki film, EVER! (at least, I think that's true . . . . )
Now, the bad points. I don't think this is his best movie. I think the plot was either too jumpy, or maybe it was just lacking something that the greats Princess Mononoke and Spirited Away had. I wasn't completely FLOORED like I was with those movies. Nonetheless, even Miyazaki's "not-best" movies are heads and tails above the rest of the crap in the theaters lately. If I hadn't seen the superb Batman Begins right before this, I would have said that this is the best movie I've seen in a LONG time.
One last note: My jaw dropped when I was watching the credits and saw Crispin Freeman listed as the voice of the Turnip scarecrow. Or at least, I believe that was who he was listed under. Still, you normally don't see the usual english anime voice actors in Miyazaki dubs. Freeman must be dancing with joy for landing a part in this. Even if it only was about six lines or so . . . . .
