When 'Niagra' was released, The New York Times praised the film, if not the acting. They wrote, "Obviously ignoring the idea that there are Seven Wonders of the World, Twentieth Century-Fox has discovered two more and enhanced them with Technicolor in Niagara... For the producers are making full use of both the grandeur of The Falls and its adjacent areas, as well as the grandeur that is Marilyn Monroe... Perhaps Miss Monroe is not the perfect actress at this point. But neither the director nor the gentlemen who handled the cameras appeared to be concerned with this. They have caught every possible curve both in the intimacy of the boudoir and in equally revealing tight dresses. And they have illustrated pretty concretely that she can be seductive - even when she walks. As has been noted, Niagara may not be the place to visit under these circumstances, but the falls and Miss Monroe are something to see." Although it was not written as a star vehicle for Marilyn Monroe, she would dominate the film nonetheless. Along with 'Gentlemen Prefer Blondes' and 'How to Marry a Millionaire', it solidified Monroe's status as a bona fide box office draw.
