Strip away all the supplementary material, and judging him exclusively on the movies, I must say Boba Fett is amongst the most overrated characters in Star Wars.
The only thing he has going for him is the undeniably cool looking suit of armour. Apart from that he does absolutely nothing noteworthy, and in TESB they only call him “bounty hunter”, just to show how little Lucas thought about him.
I sincerely don’t understand why he’s so popular with fans as he’s pretty much a nothing character.
