Morning's at Seven opened in the late 30s and flopped. It opened again in the 50s and flopped again. Dead and buried twice.
Third time was the charm, I think it was 1980 and it ran over a year, made money and won 3 Tonys. Within the last few seasons Lincoln Center Theatre mounted it yet again for the 4th full Broadway production and it was successful.
Some shows run and make some but not all of their initial capitalization back. Sunday in the Park With George was one of these that it was estimated returned 75% of its capitalization. Jekyll & Hyde was another long-run that closed at a partial loss as was the original Chicago, Tommy, 42nd Street revival and Ragtime among many others.
Variety classifies as a flop any show that did not at least break even. Partial return to them is still a flop.
There is a French term for critical success but financial failure, success d'estime. I haven't seen its usage in a while, but it used to be commonplace in articles and books.
