Well, if this was a new IP, or even a so-so known one, and the budget was $200M ($300M-$400M when including marketing), this would be a good result. Of course, considering this was a SW movie, and the budget was more like $300M (probably $450M-$500M including marketing), this is a bad result.
As for merch, that revenue was down in 2017 and even more so in 2018. Considering we had the massively popular Black Panther and Infinity War in 2018, SW must have been pretty low to offset the revenue from that. Then, I believe in late 2018 or early 2019, Disney rolled their consumer products division into their parks experiences division to hide the losses. Though, I think the last time I looked, that was down slightly, too. Could be wrong on that. Either way, there's a reason Disney wanted to retcon TLJ.
The lack of transparency is as always annoying. We can assume the trilogy is a failure, but only Disney really knows. In a perfect world quality would determine success, but that's not the world we live in so I have to wonder about it. Doubtless there will be another Trilogy either way.
If the extended cut is similar to Endgame, then there's probably just going to be some behind-the-scenes and deleted scenes after the credits and that's it.
From what I've heard they were testing a bunch of different endings. Could be that, and I'm definitely curious to see what they are given the one they chose was laughable.
