ABSOLUTELY LOVE THIS!
I grew up watching Toy story and it is one of the few movies I will rewatch over and over.
At first I was skeptical about watching the movie because I thought nothing could get better after the 3rd and I also thought they left the movie off at a good place to end the series. I thought the 4th was going to ruin everything but I'm excited to say that IT DID NOT!
I don't think a Toy Story 5 will be needed, however, If they can pull it off like they did to this one then I'm all in! Take another 9 years if you need to XD
