I think we're using wildly different interpretations of the word 'important', and admittedly I'm using a rather wide definition. I don't always want a story to be huge and big and the greatest; but it should at least impress me in some way, be original or new, for me to think it worth spending my money on - and often, for it to be entertaining.
This isn't impressive, original or new. It's a rerun. It's the same old endless Joker-Harley story, and it is dull, dull, dull - and to add insult to injury, it obstinately pushes aside the continuity of other books to go "No, This Is What I'M Doing".
Never mind that Dini is one of the most sexist writers in DC.
