I never liked Boba Fett.  And I'm a geek that will put his geek credentials next to anyone's.  I never understood his popularity, and always thought Boba took too much of the spotlight away from Luke and Han (well, OK, just Han...).  I was glad to see him eaten by the sarlacc beast.  As a kid, I practically wore out my VHS copy of Return of the Jedi watching Boba fall into the pit, rewinding, watching Boba fall into the pit, rewinding, watching Boba fall into the pit, etc, etc, etc.

It made me mad to later learn that Boba had been resurrected (or rather, that he never really died) in one of the many Star Wars novels.  It almost completely soured me on Star Wars.

Then when the prequels came out, I see Jango getting the spotlight and realize the Stormtroopers were all his clones (ending my childhood dream of joining the Empire)...  Ugh.  Not even seeing Mace Windu decapitate Jango made up for it.  Well, maybe just a little.  I wished though, that Mace had dropped a "motherfucker" while doing it.  That would have completely made amends in my mind.
