For me, reccing a flawed story is a matter of if the flaws balanced against the rest of the story still make it an A/A- story for me. If I enjoy the story as it is but realize that those flaws means it's not as good as it could/should be then I won't rec it. I'm a lot more likely to rec it if it has personality, if it jumps off the page in spite of all it's flaws.

I hope that helps even if it is a very handy wavy gesture kind of definition.
