I definitely don't agree. I think the praise and recognition it gets for its animation and score is completely deserved. For those alone, this movie is a masterpiece. Besides, many people say it's boring, think Aurora is bland and has no personality, and don't give credit to the three good fairies for being such progressive characters/protagonists.
Disagree. I think it's neither overrated or underrated. Plus, off the top of my head I can name three movies that are overrated; The Lion King, Frozen and Beauty and the Beast.
