I wonder if box revenue is the right way to lense the quality of the movie. Otherwise, by the same logic, I can think of several well-loved Disney animated films that would deserve being lumped into the same bucket as Strange World.
One example would be Sleeping Beauty. Budget of $6M. Initial release revenue of $5.3M. Which contributed to Disney's first annual loss in 10years and layoffs in Animation. And that's just one of several movies that didn't make their money back (at the time).
Yes, I know it's the only real quantitative measure we have but I feel too many variables are at play to draw comparison conclusions of the entertainment quality of the film.
