I guess the idea is to sell as much as you can, so if you go a bit too crazy, then people might not go for it. Like Transformers. Transformers made a bunch at the box office, so what’s a guy to do… make Transformers 2, or go for some ‘foreign language’, black and white, arthouse film full of unknowns? It’s show business after all.
Sure, it could be better, it might be a lot more creative, but is it going to put giant wads of cold, hard cash in the back pocket? Probably not.
When you’re making stock it’s all got to be pretty generic. Like if you have a crazy house interior, purples and reds and rubber walls with diamond staircases… it may be great, and it may be perfect for certain buyers, but it’s always going to be wiser to paint it white and fill it full of IKEA stuff before you put it on the market.
