Well, basicly this thread is just a cry of irritation as once again it seems that the new Pokemon will be exaggerated with random objects and signs infiltrated in their being/body(whatever you call it). I have seen the new pokemon starters and legendarys and find them together with the 4th generation massivly exaggerated and too "fancy". The reason I like Pokemon, is mainly because of the 1st and 2nd generation who had simple pokemon with no "ultra"-shields and random trees on their back. There are of course some exceptions in the 4th generation, but they are rare. Pokemon is getting uglier every generation.
Again another complain on new generations.
I will probably repeat something still said, but complains like yours continuosly shows up so:
1: I have nothing against personal taste: if you like some pokemon and others don't is am matter of subjectivity; however, I can't accept statement like yours that marks blindly a generation just because it's not the original:
2: "random things on their back" I think you was talking abaut torterra but I suggest to look to venosaur:
LOL they are so similiar
However you could argue that bulbasaur has the flower from the beginning, so I present to you...blastoise: when my wartortle evolved, I was expecting a turtle with beautiful ...ehm...waves, instead I obtained...random cannons(on his back)! The same thing with dragonair.
Talking abaut complexity there are simple and complex pokemon in every gen: in the first I would point out nidoking, magmar, rhydhorn and clefable spikes, the stripes of electrabuzz, arcanine, ariados and the others such gyrados, kadabra, kangaskan, scizor, hundoom, tyranitar.
Also, too much simpliciy can be negative: diglet, magnemite, coffing evolve throught fusion, staryu and grimer becoming bigger.
So in conclusion in all the geneation there are simple and complex pokemon and all the players should look carefully at the new ones deciding what are his favourites and not marking all as uncreative from the beginning.
EDIT: on legendaries, I have too agree that there are too many of them and a lot of unnecessary... they could recycle some of them instead creating new ones: for example at the place of regigas they could have put kyogre, and to the place of heatran, groudon, and use the awesome fire/steel combo for the starters, at the place of blaziken typing.
