A suffusion of yellow
I get that a fair number of Star Wars fans like or adore Boba Fett, but I've never seen the allure based on his appearance in either the original trilogy, the prequel trilogy, or all six movies as a whole.
I think that the allure of Boba Fett was more about what he could have been rather than how he was actually presnted in the movies and his stoopid demise in the Sarlacc Pit.
He could have been a major badass, the pale rider, conflicted bounty hunter and last survivor of his kind. He could have been a legend in his own right, but the movies wasted the opportunity. The Sarlaac Pit was just dumb and the background added via Jango was a bit naf.
Boba Fett has become cool because of fan imaginations rather than anything in the movie presentation
