Keeping this review short and making sure it's not an essay (while also not having spoilers), here's a brief summary of the pros and cons:
On the positive side, the animation was beautiful and detailed, and I was glad that Raya was not a cookie-cutter princess with different colored skin; she had a unique face shape of her own. The last dragon was lovable, and Raya was a good role model while also realistically not perfect--after all, what human is? One part made my eyes sting, and another my eyes water. It was sweet and had messages that we (everyone) could use at present, plus was a good way to get lost in another world and forget current events. The action was awesome (especially for it being animated!), and you have GOT to love the main character being a warrior princess!
On the negative side, a lot of the humor was cheesy, and despite it being realistic that Raya wasn't perfect, other parts were too good to be true. There were some cliche lines, and what would happen next was way too predictable. Biggest of all, the movie was unoriginal: Although if you summarized the plot in one paragraph, it would sound unique, it was basically a mash-up of Moana, How to Train Your Dragon, and Endgame, with touches of Mulan, Rogue One, Tangled, and Frozen added on. (Plus, this is just my opinion, but I could have used some songs.)
If I was a kid, tween, or in my early teens, I'd adore this (although perhaps find some of the action scary). But as an adult, I thought it was... nice. In short, the movie was worth watching but not anything to gush about.
