luxvesperis posted a review and a few pictures, including what the Calcifer plushies look like.
reene commented briefly in the dianawynnejones community (where there's also a post about the movie soundtrack, which is also out).
Some of my comments on the movie also came from tsutanai's viewing. (Thank you for passing them on!)
Update: The BBC reports that Howl set new box office records for the opening weekend for a Japanese film.
