I can definitely say that it is worth watching. Its approach to comedy and entertainment was really unexpected but original and iconic at the same time. It was a lot of fun and you don't get bored of it. Margot Robbie was gorgeous as Barbie and Ryan Gosling was scene-stealing as Ken.
However, the things that really caught me off-guard was the ending, and the weak relationship development between the main characters.
The ending was fine but not the one that the audience would want. This movie also tried to include some problems that real humans face such as existential crisis. But in the end, the movie itself was really really good, but a little bit not enough to be called 'perfection'. Some moments can make you laugh, but some can make you cry.
