I don’t know why there are so many negative reviews. I just watched this movie and I thought it was outstanding. The scientific aspect was interesting and the comedy from many of the characters was well timed and made me laugh out loud. As in all Pixar movies there were parts that pulled on your heart-stings, and the relationships felt real and genuine for the characters.
I know many people say this “ruined” the character buzz lightyear from toy story for them, but it wouldn’t make sense to have a sci-fi movie from the toy story world be a goofy slap stick comedy.
It was a great movie and this is coming from a true hardcore Pixar fan. I grew up in the 90s and lived on toy story and a bugs life. I have seen every Disney animated movie and lightyear ranks among the top 20% easily.
To end my rant don’t let peoples comments about this movie deter you from seeing it.
