Yes people are overreacting, I find the complaining about budgets as if they are the main problem with Hollywood odd. In Disney and DC's case, most of their flops would lose money even if the budget was cut in half, because there was just zero interest from the getgo. The key to making flops like Indiana Jones, The Marvels and Aquaman successful would just be to simply not make it. As for cases like Mission: Impossible and Fast X, we know for certain those are down to strict COVID protocols, so the complaining as if it isn't an isolated incident outside of the studio's control is again, really weird.
