Revisiting the Toy Story characters with our 4-year old grandson was a fun experience. He had not seen TS1 or 2. No worries! The story kept his interest for the entire hour, 49 minutes. To me this means, good story writing, good animation and enough action-packed scenes to hold the attention of both a healthy, active 4-year old boy and grandparents who sometimes doze off during other kid's movies.
