Toy Story 3 is movie making perfection. It is as simple as that.
It has universal themes (love, loss, loyalty), action (maybe too much for some youngsters), humor (both slapstick and intelligent/subversive), and a few tear-extracting moments (for those who have ever cried at a film). It does not dumb anything down (it even has a few subtitles!), stays true to the wonderful characters that have been developed through the other two films, and will touch a nerve for anyone who has had to move on in life, possibly leaving everything they know and love behind.
I've enjoyed the 3D craze recently, but until seeng this film I always ended up spending some time peering over the glasses to see the technical side of it. During Toy Story 3, I was enthralled every second and truly forgot that 3D was a part of the experience, I just went along for the fantastic ride.
