First, let me mention the dinosaur. It's been plastered all over the television screen, dancing and prancing around in an effort to get kids interested. The problem is the T-Rex acts like a real predator! It is trying like hell to eat people. It ain't doing a line dance with anyone, as most people would expect. One family will see the movie and tell everyone else to stay away.
Second, Pixar isn't involved. What Pixar touches is gold and it can be said with some level accuracy that lately, Disney attempts at these kinds of movies tend to show poorly (last one that comes to mind was The Wild).Overall, Meet The Robinsons is a good showing. It has a great uplifting message of "Keep Moving Forward" and for the most part it is well crafted (even if the vacuum tube idea was done in the sixties cartoon The Jetsons). While it is geared toward children (it has a G-rating) I don't believe easily upset and/or impressionable kids should see it. That is of course unless you enjoy waking up late at night to calm your kids down over the nightmare they had about a T-Rex eating their parents and dog, or, you're the babysitter so the nightmares the kids will have aren't your problem.
If you want a good movie to sit and watch with your kids, I’d wait for Ratatouille, which is due in theaters in June.
