Riedel's column says the reviews didn't affect the box office as much as they expected:
"The $14 million musical opened with less than $3 million in the bank. Monday, the day the reviews came out, sources say “The Last Ship” took in a little more than $100,000. On Broadway, the minimum threshold for a new musical’s opening day should be $250,000, maybe $350,000, given the high weekly running costs most shows have these days.
In previews, “The Last Ship” grossed a little more than $500,000 a week — which, I’m told, is a bit shy of the weekly overhead."
