Most of the points i've read are valid, and in America it is being expolited to a ridiclious amount. But as one poster said, its just another form of medium. And to me just another wonderful form of animation and comic style. In the end, it willl always be about the story first then the visuals later.
To me, anime and manga in themselves aren't overrated. Even if there are some titles that are overrated, the medium in and of itself isn't, at least not to me. The titles that are overrated are really just the result of being marketed too much.
Is the medium overrated? No. If one were to apply all they know of anime from DBZ, Pokemon, and Beyblade, and say that the whole medium is overrated based on shows like that, then one could say that a lot of things are overrated. But, are there a few titles that are overrated? Yes.
So, here's my opinion, even if it sounded like the babblings of a complete and utter dumbass who has no clue what she's saying.
I say no and yes. Mostly no. Sometimes anime is overrated, like Yu-Gi-Mon, Pokémon, Beyblade and so forth.
I have to agree that anime looks very alike. It's not like cartoon. But seriously, would you like millions of different UGLY cartoons than millions of equally BEAUTIFUL animes? I don't. Cartoons are ugly. Disney used to have good art, but now they have...yuck! Look at their artstyle! Bleh.
Oh, and even though anime look the same, they still don't look the same entirely. Styles are always different. Does your anime style look the same as SmashSweetie's anime style? Nope, but their both anime, and they're not ugly.
