I would say it’s exactly what a risk-averse money-following committee would do. Regurgitate remakes of previously successful things to milk the cow until it’s powder dry.

Whether this is a successful strategy is debatable.

One film by isolation doesn't say much either way, as any given film is high-variance — look at the industry as a whole, and not just box office but total revenue.

I don't have stats for that either, so these things might well still support your claim, but that's what you have to look at.
