Your unreasonable snark has no power here. Snark doesn't make your point correct. In fact, the use of snark shows how weak your position is since you aren't discussing the actual topic and situation in favor of scoring points based off of vibes and aura.
I mentioned the condition of "break even" in the BO. That does absolutely lead to an over all profit margin on the movie thanks to post-theatrical. And that's financial success.
I also mentioned how a movie can be unsuccessful in that it wasn't widely popular and well received.
I didn't mention the situation of financial failure because the BO was so weak that the subsequent windows couldn't make up for the loss. These exist. Probably Snow White is in that category.
So, it does indeed depend on how one defines 'success.' It's not black and white, snark withstanding.
