Read this passage and identify the opinion Kamen expresses. How does he support his opinion?

I had just finished making a complicated piece of
equipment that was to be used for a show opening in
Philadelphia called "Fiorello." When the machine arrived

college that morning for an orientation, I spent several
days at the theater fixing my light/sound equipment. The
show received poor reviews, except for the mention by
one reviewer of the "special effects," which, he wrote,
were "outstanding."
