The commercial for this film was terrible. While seeing it during my screening of Tangled 3D, I didn't laugh or smile once. I thought that Imagemovers was closed after what happened with A Christmas Carol last year. Apparently Zemeckis had some money saved up to keep the company open for this and the already-planned Yellow Submarine remake. After reading the previous comments, the company's dead but why did Disney allow this film to be made? While looking at the characters, I didn't feel attached to any of them. The well-rounded guy who was, I think, in control of a part of Mars, made me think that the voice actor for him was going for a Jack Black impersonation. I didn't care for his little hunk of scrap metal sidekick. It reminded me of the land rover sidekick from Planet 51 and we all how the critics tore that film up to pieces. The aliens made me think of sea monkies along with them reminding me of the Minimoys/Invisibles from Arthur and the Invisibles/Minimoys, again another film that wasn't seen as great to the critics.
I took a look inside the book a while back and it was pretty interesting. I would recommend to anyone who wants a story to read to your little cousins, siblings, and kids you're babysitting, check the book. As for the film, I'm not buying a ticket for this even when it hits the only $4 theater close to my house. I rather see Cars 2 and Winnie the Pooh as the only Disney films next summer over this.
