Alright, I have a few to list off ...
In the series as a WHOLE?
There's Ash. Yes, Ash!
I can openingly say that I DO NOT watch the anime for him in anyway. I really couldn't care less about him. They have made it clear that he will never reach his goal and that he is nothing more than a possible doll, being posed to take on w/e role they want to force upon him. (Writers) "Oh, we're gonna bring in some newb female? Lets make him the older brother character that's a bit more mature than he use to be so that he can be the role-model. In-order to make contest more legit lets have ... ASH USE CONTEST MOVES IN HIS BATTLES! That way he can have a stupid hex dodge via yelling "SPIN!!!" and BAAAM, the Pokemon HEX DODGES and everyone watching with their mouths open and their chins to the floor as his pokemon SPINS out of harms way like some fancy Air Bender! Oh, no more newb girl-to-take-on-contest because there's no contest in this region? Well, lets make him a lil kid again thats all newby like his Kanto days! REBOOT!!!!!". I only watch for ... pretty much anything NOT Ash. I watch for the Pokemon, I watched for the contest, I watch for Iris and Axew, I watch for fun stories ... but Ash is just there. I don't HATE him ... I simply don't care about him. And given his role I feel that not feeling ANYTHING towards him is just as bad as not liking him at all.
Then there's TR.
Man, I have been watching some old AG episodes ... I noticed that I would think to myself "Man, I like where this story is headed! Whats gonna happen ne-" then I see the "twerps" through a pair of goggles and then I think "F***, not this **** again ...".
I truly don't know WHY they care so much about Pikachu (other than the fact that they HAVE TO because its the only Pokemon that's gonna be there no matter what. It's their "Anchor" to the show until BW). In the 2nd episode Pikachu blew up the Pokemon Center after getting power Pumped by not only a gang of Pikachu on-top of it but also by Ash riding that busted up bike. Really, I think the Boss would just send Pikachu back to them if they ever sent it to him. Their gags arnt funny, their nothing but punching bags and they have outstayed their welcome.
BUT they are one of the main things BW has done right in it's attempt at rebooting the show. No longer are they around EVERY EPISODE. No longer are they gags/ jokes. This is how they should have always been.
Also never liked Brock or his never ending changing career goals but he is gone now so "YAY and never come back ...".
I didn't HATE hate him, he just annoyed me greatly and I can't think of one character from that time that annoyed me as much as he. Mainly because regardless of the fate that he's a know-it-all he doesn't have the ability to catch or raise. I never cared much for him and I didn't MIND him being there, he just annoyed me cause I didn't see much reason for him to be there other then to show off how lazy May was with her studies. He is by far the most likable on my list, I really like AG now that I watch it a bit online (I skipped most of it because I hated the 3rd gen of Pokemon Games).
DAWN and PIPLUP!!!
Dawn ... yup. I hated her. She brang nothing interesting to the group dynamic. (Thats one reason I LOVE Iris, she's a snarker who points out the annoying traits or actions of the group. She's pretty much my voice in the anime when Dent does "it's Blank TIIIIME!". Having clashes and conflicts between people who clearly care for each other even if they don't always get along is the right mixture for a great group IMO) Really, it just felt like everyone was standing around patting each other on the *** in DP. She made contest lame and more SHOW than substance.
On top of that she has that logic breaking skirt that makes her look so flat and strange when they try to pull off those cam angles that should logically show up her skirt by drawing her in a way so that you can never actually see where the legs meet. GG, it was a stupid design in the games too for someone to wear while travelling. If its gonna be that much of a problem why not just give her shorts to wear under her skirt?
I did not care for Dawn's whinny lil baby act nor her flashy-girly style nor her Pokemon. Heck, once it became clear that she would never make Buneary happy enough to evolve I dropped out of DP.
Piplup is and attention hungry annoyance. He doesn't deserve a proper explanation.
And finally ... for BW!!
It's ... BEL!!!
I tell ya, if Paul treats Pokemon like tools then she treats them like Beanie Babies. Spoiler:- BW INFO:
