Yes... There ARE too many of them...
Its almost like..they're not special anymore... D:
It doesn't matter how many legendaries there are, what makes them legendary is that there is only one of them. Thats what makes them so special, plus, for each legendary pokemon, there is a story to be told, a legend. And even today, there are hundreds of legends, myths, and stories about legendary beasts and monsters that where, and do exist. Even though some didn't exist, we still believe. The same goes for Pokemon. So saying that there are to many legendaries, or that they aren't special anymore is pretty rediculous. They will always be special, and they will always be a legendary.
Example.
Beowolf.
Beowulf is a story about a monster named Grendel, who terrorized the land, and people of the middle ages. Though no evidence exists, there is a castle in britain or whever ever. And near the castle is a cave, and in the cave, dead corpses of humans where found. But the most astonishing find was a corpse a monster like creature. Kinda sounds like Grendel if ya ask me. Know, when I found that out, I was in 3rd grade and I was watching a program about the most haunted places on earth. So don't ask me any questions about that, M'kay.
So, don't say that there is to many legendaries, and don't say that there not special anymore, why, cause they will never be those two thing, never.
