*shrugs* She didn't really endear me, or offend me, because as you accurately put it, they kind of made her a nothing character. She was just...there. I think she could've been good, but she didn't even survive one film so....*shrugs*That's my main problem with Holdo. She's a waste of space and nothing character that has no reason to exist. Other than some type of "subversion" of a traitor plot twist, and a complete unintentional annoyance to the audience. I found her more annoying than Jar Jar Binks. I admit it. Holdo has some defenders and fans, but not many.
And personally I've found Jar Jar to be far less of an annoyance than I think he is made out to be. He's actually got one of the bits in Phantom Menace that I think is genuinely funny. The bit when he has his hand stuck in the pod engine, but his tongue is numb, and he's trying to call out for help. I thought that was some really good physical comedy really. I've come to actually like Jar Jar over the years, to some degree. I like that he was immediately friendly to all the droids when he went into the droid room "Hello Boyos!!" *waves happily at them, treating them like actual people* *Droids chirp back in greeting, one and all*
But yeah, Holdo, very missed opportunity there.
