Said this in the weekend thread, but I cried 4 different times here. When Brightbill first left for the migration, when Brightbill told her mom how much he loved him, when Roz left the island, and the final ending when mother and son reunite. This was made for all the autistic runts like me who love their mother way too much, and it wrecked me hard. This is the kind of movie I wish came out when I was a kid.
Though I will say, and this is very obviously a nitpick, it is funny how all the animals all decide to make a truce and be nice to each other...so what did the predators eat during all that time? What do they still get to eat? This is like Zootopia where they never answer something that stupid grown adults like me care about and it's hilarious.
