I personally thought it would be exciting to watch but turns out it was not. I could already guess the rest of the movie by watching the first half. The only reason i kept going was the acting. Gosling and Robbie were great casts and they fit perfectly for the roles, but i didn't really like the rest of the cast, specially America Ferrera and Ariana Greenblatt. On the other hand, the way they staged Barbieland was amazing! Even though i'm not a big fan of bright colors i loved how they used the typical barbie pink everywhere. In the end, i wouldn't call watching it a "waste of time", bit its definitely boring to watch the full movie.
