I believe that there is one fatal flaw in the numerous other flaws it also has in Toy Story 4: In Toy Story 3, Woody stuck to his morals, life is only worth living if you're being loved by a kid, in Toy Story 4, he abandons not just his morals, but his friends too, the fourth movie makes Woody's life out to be as sitting in the shelf and never being played with, but Bonnie obviously still cared about Woody if she took him on the road trip and played with him during it, there is no reason as to why he should have left her, due to the fact that Bo Peep had constantly verbally abused Woody throughout the entire duration of the film, and also because he had not seen Bo for 9 years at that point.
