She's always been like that, if she doesn't like it, its tit and no one should buy it but she does it under the "I'm just being honest, you'll thank me!" like she's doing you a favour.
She was very vocal about some brands when the kids were babies, some of which I loved but she was telling everyone not to buy and that they were tit. Especially about bottles, some brand suit some kids and others don't, it doesn't mean they are tit. Id say she is insufferable to be around if she doesn't agree with you. Its her way or no way.
I happened to love Barbie, but the fact all she took away from it was Margot Robbie was hot (which Im sure she would hate Aoife, she was a fierce fighter for the movie to be made and to get producers power for it) shows how shallow and vacuous she is. You'd think someone who wants to be a pilot would have appreciated the message to girls about how they can be anything.
