The Rock?? :D
For the last time, BW is NOT a reboot.

Shafted characters for obvious reasons.
Both, because overexposed characters hog the limelight and shafted characters are people you want to see more of, but don't get to. But I voted for overexposed.
For me Takeshi was overexposed (haves three series of appearances) but I can see why people have put him as shafted. The thing is that he had lots and lots of screen time but most of it, is spent standing around. For me this is as annoying as when a character is forced in your face all the time. It's the same with Iris (at the start of Best Wishes since I haven't watch for ages). It was pretty hard not to notice her on screen and therefore easy to notice just how little she was doing. This makes the characters seem less real and more stilted.
So overexposed even if it isn't 'in your face' overexposed like Potchma is the more annoying to me.
Misty and Brock were like overexposed (due to their mass of episodes) and shafted at the same time, (due to their limited screentime) In some cases it was the worst of both worlds. :p
I think it's more annoying for Pokemon rather than humans. Overexposed characters, like Oshawott, Piplup, and Tepig are more annoying since they take away screentime from other more deserving characters; such as Unfezant, Palpitoad, and Stunfisk. I think this was most obvious and greatly executed in the Junior Cup where the Piplup and Oshawott rivalry took away from the screen time of Dawn's other Pokemon.
The result: a useless comeback of a character and underdeveloped Pokemon.
Overexposed for me. It's just painful to see some chars start of so well and go downhill for me.
Good examples are DP Brock and BW TRio, IMO.
Both have their problems, but overexposed characters are more irritating, especially when the characters in question are annoying to begin with (Team Rocket and Dawn's Piplup to name a few).
Both cases have their problems and can be annoying, but I'm going to go with overexposed being the worst of the two. It can make the characters more annoying to deal with if they take up so much screentime, it causes other characters to get the shaft. Shafted characters are usually wasted potential, which is annoying to deal with too, but it's usually less annoying for me because I'm not bothered with them getting screentime, unlike with characters who are overexposed.
Overexposed - After watching them go on their journey for over a year it can be annoying too see them basically accomplish nothing.
Definitely overexposed. Overexposure can ruin a character for me completely. At least characters I feel were neglected, i'll always think of positively.
Overexposed definitely ruined Piplup. At the start of DP everyone loved Piplup, but once it started staying out of its ball and starting getting forced in all of Dawn's major episodes it became a drag.
I hate when characters are overexposed more. For example, it seemed that the writers liked Lance better than Steven and Wallace, so they put him in the Kyogre vs. Groudon episode instead of giving Steven his rightful role. It makes no sense, since I'm sure a lot of people were waiting for Steven. But that episode was flawed anyway. It was clearly biased in favor of Groudon - it portrayed Kyogre as the villain. And since I like Kyogre better, that pissed me off.
Honestly, I thought Paul was a bit overexposed too. And he was definitely a Villain Sue. I hated how other Trainers (even CYNTHIA!) gave Paul praise for his cruel battling style.
Cilan is quickly going into Mary Sue territory as well. The writers give him countless skills and positive qualities, while not giving him any realistic flaws. (In contrast, Iris gets nothing but flaws. I would say that BW's lameness is more Cilan's fault.)
