Hawkman doesn't sell as well as some other comics. There's no denying that fact. There are several reasons for that of course. DC Comics barely promoted the recent Hawkman series after the first couple of issues. After starting with over 40k in sales, the lack of promotion, the uninspired Year-of-the-Villain event, the pandemic, and other things gradually pulled the series down to around 12k in sales and it was finally canceled after 29 issues. One of the reasons could be that many don't like the looks, background, or overall setup of Hawkman. There can be many reasons.
When a writer takes on Hawkman his job is to make Hawkman a relatable, exciting, attractive character. He can maybe give the character a new look, new powers, a new origin, a new base of operations, a new lover, new villains, etc. He can reach into that hero's past and change and "improve" him in a way that he thinks will make the character better than before. That's just common sense. That's what every writer wants to do. Sometimes it works and sometimes it doesn't.
