The only thing that is really disappointing in the movie is Penny's vocalizations redubbed by Miley Cyrus. In what appeared to be a political move by Disney, at the last minute it was decided to replace the original Penny, voiced by Chloe Grace Moretz (Kick-Ass, Diary of a Wimpy Kid, Hugo) with Miley Cyrus. At times I couldn't feel the necessary emotion from her interpretation of the character but this was not enough to bring the rest of the movie down. While you only get to hear a few brief moments of Chloe's work, it is enough to give a hint as to how the rest of the movie could have been. Mark Walton lends his voice as Rhino, the hamster that helps this movie by being unintentionally funny in a way that adds to the film with both his delivery as well as the dialogue he provides. Additionally John Travolta's work as Bolt was exceptional. He is able to deliver Bolt's lines as we watch Bolt mature from the beginning of the movie to the end. The soundtrack improves the mood and adds to the emotional climax that should leave you in tears of joy.
The 3D version is one of the best 3D movies I have ever seen. This movie was obviously written and created for 3D, with the increased depth of field the main use of it, and is used properly, adding to the story without resorting to the old fashioned 3D tricks. At the same time, the movie does not lose any brightness in the 3D version, and the colors are outstanding. The surround sound audio completes the whole 3D effect leading to another one of those movies you must have if you have a 3D TV. It really makes you feel like you are experiencing the story and not just watching it on TV.
The 2D Blu-ray includes several bonus features. "Super Rhino" is a short featuring Rhino who has been tasked with saving Penny and Bolt from Dr. Calico (the villain from the TV show), ending with him singing a Hannah Montana song. It also includes deleted scenes (which never made it past storyboarding), a music video and making of it featuring John Travolta and Miley Cyrus, a "behind the microphone" featurette, a game, and several making of featurettes as well as art galleries. The combo pack also includes a DVD copy of the movie as well as a digital copy of the movie, making this an extremely good value. Now because of the quality of this 3D release, even if you have the original 2D Blu-Ray release, and you don't have a 3D TV yet, you really should consider getting a copy of this release as you won't regret it when you do pick up a 3D TV. And if you do have a 3D TV, this movie should be on your shelf.
