This movie was amazing!
Yes, it is mainly a romance movie. A majority of people leaving one-star reviews are saying it's boring/falling asleep.
If you're expecting a movie like 'Lightyear', then this one won't be for you... and if you're comparing any movie to a terrible movie like 'Lightyear', then maybe don't watch any more movies.
This movie is more in line with 'Soul', where it focuses more on character dynamics than action and adventure.
