The blind man can be an "excellent "victim in the thriller genre : see David Eady's "faces in the dark" (1960 )and Henry Hathaway's " 23 paces to baker Street "(1956): "blind corner " borrows the "in the dark,we are equal " from the latter (a trick which would be used again in "wait until dark" (1967))
That said ,the screenplay is not as exciting as the aforementioned movies : it drags on in the first part ,and the syrupy songs are filler .But it hits its stride in the second one,full of sudden new developments ,with a good cast including excellent William Sylvester ,people outside England recall as "2001" doctor Floyd. He is very convincing as a blind man who's got some kind of "sixth sense" .
