The movie was touching and heartwarming. I shed some tears watching it.
However, I would say two minus points about this movie - the expressions of the animals cannot be conveyed properly, though understandable since they implemented realistic styled movie. The second one is the lore - the lore is totally broken! I watched Lion Guard and compared to Mufasa, the way Taka got his scar is very different! Even Lion Guard didn't really respect the already existing franchise - but Mufasa movie strayed too far. Where's Ahadi and Uru - Aren't all of them royals?
At the end of the day, this movie is fun, entertaining, and educative to watch with your family (I'd say it's PG-13) - but Lion King lore lovers would complain a bit or two.
