Absolutely fantastic movie! The animation and storytelling are phenomenal. The visuals, worldbuilding, and dialogue work together SO smoothly. (I cannot emphasize the animation quality enough). I was hesitant about the voice actors, but they didn't take away from the watching experience in the slightest. I think the voices added to the already fantastic vibe of fun. The whole movie is pure fun.
I don't play the game but my lack of knowledge wasn't criticized, while at the same time, I didn't feel like it was spewing references left and right to try and teach me something. The aspect of the game itself blended in amazingly with the plot. I don't think any viewer, gamer or not, would feel belittled. The movie treated its audience well.
This is a quality film I would watch a hundred times. I've been waiting for a good kid's movie for a while and this blew my standards!
Top tier!
