Like you'd expect from a film set in a kid's bedroom, Toy Story has a large ensemble cast ranging from action figures to wind-up mini-binoculars. This means that, while Woody and Buzz are objectively the protagonists of the story, we're dealing with an ensemble piece, something the series is getting increasingly bad at realising. The first cracks of this came in Toy Story 3. Aside from Woody, no character had any real development, with Bullseye getting only a handful of moments and Jessie made less important than Mrs. Potato Head. Even Buzz, who was a central character in the original two movies, was reduced to a supporting character - he has no development (deux ex machina transformation doesn't count) and could be easily removed with little effect on the story. And all this happened despite many of the extraneous residents of Andy's bedroom being written out between Toy Story 2 and Toy Story 3, leaving a smaller cast. There seems an inability to keep more than three characters involved in a scene at any one time. The shorts have continued this, with each one only focusing on a couple of characters, with the rest only cameoing. This wouldn't be terrible, if it wasn't for another major issue in the writing of the characters...
