It'll never not be odd to me to see how eager people are to defend the giant studio making unilateral decisions with 0 regard for the creatives or business partners involved. People act as if WB was doing something noble here, when it was simply them viewing this as an opportunity to inflate that value of their suscription service...which is a decision that benefits them, while offering no such benefit to all of the above people involved, who had signed up to make a traditional theatrically released film.
Delaying the film was an option on the table. The film may have bombed anyway, but that's not the point. It's the principal. WB's move last year was still bad form.
