It all depends on how much the movie cost to make. Butler’s reported budget was $30 million, so a $25 million opening puts it on a solid path to profitability. Lone Ranger cost $215 million to make so its $29 million opening makes it a bomb. Yes movie revenues are graded on a curve, but that curve is the budget.
IMHO even if they spent 20 bucks on it... it is a failure... at least in truth.
