Disney owns way too much. They can bully theater chains to show their films on as many screens as they want for as long as they desire, and then they take a lion's share of the revenue.
Disney can print money from all of the licensing, which isn't a problem save for the fact other entrants have a huge hurdle to overcome to get shelf space.
They water down their content for mass appeal, so it isn't artistically interesting. They also appease foreign governments like China. Again, it wouldn't be a problem if they weren't strong arming others out of the limited theater space.
Disney+ kicked off the streaming wars. Which is going to be fantastic as a consumer... :(
Disney is ridiculous. I say this despite the fact that I have a good bit of stock in the company.
