When Toy Story started, I was around one-year-old. Sadly, though, the movie didn't stick in my memory, and even though my parents tell me that I loved it and watched it dozens of times on tape, since I saw it so early in my youth, there were no memories to be nostalgic about.
I ended up seeing it for the first time in memory only after Finding Nemo, what I still consider the best Pixar movie. After so much more that Pixar had done, it didn't stand out to me as any more of a masterpiece than the rest, and Toy Story 2 ended up making me resent the series.
In a way, I hate Pixar making sequels. What I love more than anything they do are the worlds they create, and with a sequel, there's not a new world to explore. Sure, there are new concepts within the story to discuss, but in the end, a new setting will always allow more depth.
I plan on seeing Toy Story 3, and since it's a Pixar movie, I know it will be amazing, but I resent that I can't look back on the series with as much love and adoration as those who were older and could remember the original, and I resent that it's no a new world. Next summer, maybe we'll get to see another beautiful setting from Pixar.
