Okay, fangirlishness aside, this movie is very well done. The animation is fantastic, and though I've only seen it in English so far, the US voice acting is very good.
The movie starts off with young Shawn, voiced by David Henrie, arriving at his aunt's house for some rest and relaxation before he has to go through an operation. He settles in, and the movie turns to what effect his stay has on the Clocks, the borrower family living in the house. The story and characters are well fleshed out with their own desires and dreams.
Will Arnett, Bridgit Mendler and Moises Arias are great as Pod the father, Arrietty and Spiller, but it's Carol Burnett as the miad Hara, and Amy Poehler as Arrietty's mother Homily, that really steal the show. It really sucks you in, and if it weren't for the beautiful animation on the screen, you'd think it was really happening. That borrowers really do exist.
And now for the bad side. This was the ending song for the original release
It's a beautiful song, I love it, but Disney, again like Ponyo, went with a translated version sung by the main character shown here.
Not the best, and it was kind of a jarring end to the movie as the credits roll. The rating I'd give this is 4.5 out of 5 stars. Could have been a 5, but the ending just doesn't cut it Disney.
