*im probably gonna be shot for this*
actually i've noticed that the show is becoming less sexist.
when the show began the show compleatly revolved around ash, but now the (not so) new heroine (dawn) is getting more attention. well it says so on bulbapedia anyway ._.
altough i wish they would involve characters like lucas and brendan more... (well more then cameos anyway)
Err... I won't say that it "Completely revolved" around Ash in the earlier shows, since, if it did, episodes like "Princess vs. Princess", "So near, and yet so Farfetch'd", "Who Gets to keep Togepi", "The Misty Mermaid", "Beauty and the Beach", "Bye, Bye Psyduck", "Go West, young Meowth", "Pokemon Emergency", "Tentacool and Tentacruel", "Pokemon Shipwreck", "The Waterflowers of Cerulean City", "The Mandarin Island Miss Match", "Misty Meets her Match", "Stun Spore Detour", "For Cryin' out loud", "Hook, Line and Stinker", "Trouble's Brewing", "The Joy of Water Pokemon", the majority of the Whirl Islands Arc, "Some Like it Hot", "Gotta Catch Ya Later", "Showdown in Pewter City", "Clefairy and the Moon Stone", "Bulbasaur and the Hidden Village", "Charmander the stray pokemon", "Make room for gloom", "Pokemon Fashion Flash", "Heartbreak of Brock", "To Master the Onixpected", "Poke ball Peril", "A Tents Situation", "The Little Big Horn", "Going Apricorn", "Love Totodile Style", "Hassle in the Castle", "Beauty and the Breeder", "Sick Daze", "Control Freak", "Entei at your own Risk", "Just Waitin' on a friend", "The Totodile Duel", "The Breeding Center Secret", "The Evolution Solution", "Illusion Confusion", and others wouldn't have ever existed. (BTW, it focuses on Misty, Brock, and Team Rocket, and my sources are from both Bulbapedia and the episodes themselves.)
Now, their not giving Characters like Lucas and Brendan main roles in the series isn't sexist (Though that doesn't mean it isn't pointless, as it IS pointless, as Ash is getting staler by the minute, among other things.). However, their viewing the female characters as being expendible and even going as far as to simply rehash their goals all the time while allowing to keep the same male protagonists, yes, that's undeniably sexist. What's even worse is that Masamitsu Hidaka revealed that the reason why they replaced Misty (and ultimately, why characters like May and Dawn even exist) is for eye-candy/boytoy purposes, which is a very shallow and sexist reason, in and of itself.
