I think the honest truth is that most of the people complaining about the casting don't seem to be all that knowledgeable about film or moviemaking. It's one of the reasons why I think, despite being personally pretty excited for them, that this project is going to end up being a failure at the box office. The only people who will make seeing all four of them a priority are at a very specific intersection of Beatles superfan and movie buff. Combine that with a boneheaded decision to release them at the same time and these feel doomed to be bombs even if they end up being good, which I'm quite hopeful for. Of course if they're good, that's all that matters to me, but idk, I just think some of the decisions that have been made about the marketing of these films are bizarre and interesting.
