Finally got around to watch it, my wife wanted us to go home after around one hour, and then again when Kens started dancing towards the end. It wasn't slow, but the plot was really shite and it's just an average movie. So many clichés and cheesy lines and obvious jokes, the jokes were on level if someone asked Chuck Lorre to make a feminist parody of Two and a Half men. First hour of the movie apart from first 15ish minutes was decent, but last hour was pretty shite.
Production was nothing special, those posts about shortage of pink colour, etc. was obviously bullshit as many things look to be CGI anyway, and the Barbie world was pretty small. All in all, 5/10 at best, and that's because they included entire Sex Education cast(what's with that?).
Saying that, I am absolutely surprised by lack of praise for Margot Robbie for this movie. For all people who pretend it's a great movie, hardly anyone put any extraordinary praise for Margot who deserved it. After this and Babylon(absolutely ridiculous performance), she is already one of GOAT actresses(including male actors too), IMO. She is absolutely phenomenal, her range of emotions is just ridiculous, her face and smile is something else, and not just from looking pretty point of view. She is just excellent actress. I actually wouldn't mind if she got an Oscar for this movie(I know it's impossible, but anyway).
