Possibly my new favorite Studio Ghibli film! A perfect blend of characters, atmosphere and narrative, The Secret World of Arrietty seems to have found the secret sauce that other films just could not.
The atmosphere and world-building is top notch here, and everything is so detailed and wonderfully created there's a real sense of personal detail by the film's creators. How these small characters navigate, work, build and live day-to-day is incredibly intriguing, and as I'm sure many others have stated, I could watch an entire film of just their day-to-day lives.
But the icing on the cake here is a simple but meaningful narrative, one where the story is building to certain points but develops a personal and emotional thread that closes the final act of the film.
Lastly, the characters are all wonderful too, with each one a distinct personality and memorable presence in the film. This film is an absolute delight, and deserves a viewing.
