How commercially successful, in general are Mockbuster movies?
In a previous answer, they state that Mockbuster movies are made cheaply to turn a quick profit. Quoting from that answer and Wikipedia:Mockbuster :
Mockbusters are often made with a low budget and quick production to maximize profit.
There must be a good commercial motive to make and market these movies; however, it is difficult to find any clear business analysis of this "genre".
Edit:
A question in the comments by Luciano:
It seems some mockbusters are more successful than others, so how to get a "General" overview of the genre? How do you determine a commercial success in this case? Based on its own costs or compared to the original being copied?
I naively would say something like "profit is revenue minus expenses" but after looking at the Hollywood Accounting wikipedia page, it seems like that won't work at all. Perhaps "gross revenue minus productions costs" will work? I am open to suggestions though, about how to count this.
