Toy Story 3 - *sigh* 6.5/10. I really wish Pixar had stopped after The Incredibles because they haven't had a really good movie since then (though there are flashes of brilliance here and there).
This is easily the worst of the Toy Story series. Easily the least humorous, the least interesting, and least original. Again, they rehash the "are we being thrown out" storyline. While it was good in the first, and had strong enough legs to make the 2nd work, it is a worn out premise IMO.
There's nothing really new here, it's the same old story. And while that may not sound bad considering how good the first two in the series are, it doesn't do the same old things nearly as well as those movies did. And what little that is new (the bad toys) aren't nearly as interesting or fun as the toys they replaced.
Ultimately, just another overrated Pixar movie.
And don't bother with the 3D, it is VERY minimal in it's usage, so much so that you can almost watch it without the glasses and still see it fine. So if you can, save your money.
