This is why Wall Street has also finally come around on the parks business after years of overleveraging them to fund other businesses. They provide predictable annual revenue, expansion operates in fairly obvious ways, and the mechanisms for success are less opaque and more broadly applicable than the mechanisms behind what makes good entertainment.
I will say Universal has largely been fiscally responsible with their film business, and haven't had the spate of bombs and failures that have plagued other companies like Disney, Warner, Paramount, Sony, etc. The bigger problem is going to be their debt load and the streaming service, each of which will exacerbate the issues with the other.
