I'm pretty sure I read somewhere that if GL thought he would have been so popular he would have made Boba a bigger character.
That said, I like him. But only like. He is cool, but again, some things are just to ridiculous.
here's the quote you are thinking of
"In the case of Boba Fett's death, had I known he was gonna turn into such a popular character, I probably would've made it a little bit more exciting. Boba Fett was just another one of the minions, another one of the bounty hunters and badguys. But, he became such a favorite of everybody's that, for having such a small part, uh he had a very large presence. And now that his history has been told in the first trilogy, y'know, it makes it even more of a misstep that we wouldn't make more out of the event of his defeat, because most people don't believe he died anyway. I'd contemplated putting in that extra shot in where he climbs out of the hole, but y'know I figure that's . . . it doesn't quite fit, in the end."

not that he would have made the character bigger just his death.
