This is unacceptable at a reputable conference.
The key weakness of the paper is that it is underwhelming and thus a weak candidate.
While I think you described and executed your ideas well, I don't think this is a worthwhile research direction.
I have rarely been so disappointed by a paper. What a great topic, what a great abstract and introduction, and then what a letdown. I totally agree that this is very worthwhile work, but the paper that was delivered falls flat on its face and doesn't deliver on its promise.every paper here has gone on to be published lol
