It is a good one time watch movie. I think critics are just focusing on bad aspects whereas movie has enough good aspects to make it a delightful watch. Very few dialogues are not upto the mark because they are introduced to uplift the tone and not to insult anyone .
I would say 70 % of the VFx are very good and rest are not that good.
People who r not liking this movie is because they are comparing it with the old one.
This movie has enough merits of its own , Very good attempt , could have been more better .
