Pros:
Animation is jaw dropping.
Kept to the original most of the time (did you really have to mess up "can you feel the love tonight"?..)


Cons:
Voice acting was atrocious. Expect for Seth rogen who did Pumba perfectly, the rest were just way off. the voices didn't match the character and didn't feel true and organic and had no emotion.
too dramatic & kitschy..
I know it's supposed to be dramatic and kitsch at times but it felt forced and idiotic. you could only roll your eyes each time and say "ohh.. It starts with over the top dramatic background music for like half of the movie, and continues with the "101 script writing course" lines that are just pathetic..
