You can seethe all you want but pokemon being designed by a group of 4 guys closely collabing with eachother at the same point in time has a very different feel than a giant clusterfuck of over a thousand creatures by dozens of people over the course of decades with completely different sensibilities and marketing direction all lumped together as part of the same universe.
Sure you can say there's more to choose from and something for everybody but it also means you have to just ignore huge chunks of all the things you don't care for or dislike whereas with the original 151, sure's there's gonna be some you like more than others but it's much easier to accept them all as part of a cohesive universe.
