I didn't hate it like everyone else did, but I understand why people didn't like it even if I don't agree. I thought it was a fun movie, separated from the main canon by being an in universe Buzz Lightyear movie.

The problem boiled down to the fact that most people who grew up with the Toy Story movies all have their own ideas about what a Buzz Lightyear movie should be, and those ideas and expectations prevented a lot of people from just enjoying the ride.

I feel like years down the line it'll get a better shake and be a cult classic.
