Ok, my $0.02 :)
I'll start with the popular hated ones:
Swoobat and co. Yeah, just, why?! But it has its charms (I don't see them).
Corfagrigus, I like it. I don't know why people are screaming so much about it, there has not been any direct pokemon related to egyptian mythology and I love this. I actually really liked Corfagrigus but its defensive stats are just too obvious for me, and I like offensive pokes more :)
Sigilyph in my opinion is new and attractive. I love it with my heart, and its even in my white I team :)!
Rubbish evo tree, Is just plain weird. I can say why people would like it, but I don't. Trubbish can be cute if it weren't a small garbage bag :D
Druddigon looks both awful/weird, and strong/hard-headed. I liked how they represented it, just not the colors. (Seriously? Red head and blue body? Doesn't even fit haha...)
Stunfisk is kind of a trick pony, 90% of people won't like it. 10% will have that special taste for poke and like it :)
Vullaby and co. I don't like it. Can't see why people would choose it over Braviary, but well, there must be a female counterpart to it and I like them to think that way.
Ferrothorn. I think this thing looks badas :D Never seen typing is a plus.
Klinklank. Just... Why? Magnezone is superior every way in my opinion. But I like the pure-steel type. IF it weren't so slow and so simple. I mean... Klink, then Klank, then Klinklang? Rly? XD
Eelektross looks quite fine and I like it.
Throh Sawk. These two weren't the best when I saw them. But I loved their personalities in the anime, specially one being light-minded and more of a freelancer, and one being serious and more down-to-the-ground.
Unfezant looks weird specially after Staraptor appeared. The raptor is so much cooler.
Elemental Monkeys. These guys look really cute! Until they evolve. Except Simisear. It is derpy as heaven. Simisage gets a special mention to his Elvis Hair. It is... ELVIS PARSLEY. HAHAHA ok I'll stop.
Stoutland is just pure-beard awesomeness.
Beeheyem looks special. It is unique in my opinion.
Victini looks like some kind of thingy doing thingies. I don't find it attractive nor unique.
Watchog is high. :(
The ice cream is just weird. It's cute though.
I don't like that people just insult other pokemon because of their own liking, so I came here to point out that it's not nice to do this :D I always say that IMO, or my two cents, or Theres a Reason... Because you know... There's always a reason :D Personally I don't dislike Stunfisk. It's a sole fish, what can you ask? It has got nice typing too.
Good luck guys! :D
edit: Got long :O! I love writing long posts :D!
