As far as a "faithful" adaptation this movie knocks it out the park, it's a Must watch for anyone who enjoyed the original movie.
Sure some of the actors don't bare full resemblance to the originals, but that's on purpose, the casting was designed to sound like the original voice acting cast, but the costume and set design is amazing, each location is made by a whole group of people instead of relying on CGI, making a believable and stunning set design.
Overall, if you enjoyed the original, or just like the general premises, it's a great joy, no bad points or issues with the movie itself, and is just generally entertaining.
5/5 stars
