If you’ve spent a significant amount of time widening the scope as far as possible to include everything interesting about your original question, and there is nothing in that whole widened scope that the audience will give a shit about, your topic is unsaveable and your advisor is a failure.

If there is something interesting enough to qualify, then reduce the scope as much as possible. It should go without saying that you shouldn’t throw out the interesting bit.
