Film director: It’s inaccurate to say that filmgoers stayed away from my film because it received one or two negative reviews.
Curious Fact
Why did this film have such a small audience during its opening weekend?
Director's Explanation
It wasn't because it had a couple negative reviews. It's because it was competing with several other films that share the same audience, and it's a pretty small audience.
Evaluate
Whenever we're evaluating an author's causal hypothesis for a curious fact, we have two different pressure points to consider: 1. Alternate Explanations for that curious fact 2. the plausibility of the author's explanation
Goal
Since this is Strengthen, we want an answer to either
rule out an Alternate Explanation for why this film had such a small audience during its opening weekend (e.g. "There wasn't a terrible storm that kept people from going to the movies that weekend)
or
increase the plausibility of the author's explanation (e.g. corroborate the story that the intended audience for this film was split between seeing this film and seeing several other films meant to appeal to the same niche).
