The biggest problem with this film...
... in my humble opinion is that it focused too much on Iago. It's like Iago is the main lead and Aladdin is the second lead while Jasmine is relegated to almost being a side-kick like Abu.
To me, this film felt more like a Iago spin-off than an Aladdin sequel.
Mr McGee, don't make me angry. You wouldn't like me when I'm angry!
