I agree with this. Also, the Canary cry is visually rather dull and despite it taking action of her behalf, it just looks rather passive. And comics are visual medium.
Canary's cry isnt the equivalent to a high pitched alarm/siren/etc...it's also a super strong high pitched cry. Just as The Flash should be faster than Superman, you should be able to enlist a group of various heroes that could practically act as their own Superman hit team if paired together. Flash can outrun Superman, Canary (should) be able to blow his ear drums/leave him disorientated, Diana should be able to take him on hand2hand, Green Lanterns should be able to hold him in place for x amount of time, etc..
