I believe it is diligent to consider the market majority, on a domain. I've got a domain (Doh Name, sentimental, I think its cute) relating to Homer Simpson (D'oh! Name) . To me, its a quirky, fun way for saying "domain". However, in "reality", as we call it ...common opinion will say "that domain sucks" ...and value wise, this is a fair assessment
Doh Name may sell to a Homer Simpson fan that does domaining, making it have value. However, that is the specific buyers perception / adoration for it, than the true realised value of it to the market majority
In summary: Its demand, be realistic with what you have
