Agreed with Jimera0 and Mario With Lasers. About Satisfaction's arguments... those are silly, Charizard have great stats, now good abilities, and great movepool, and is actually great in-game, the fact that the meta doesn't like him because Stealth Rock + Insert other reasons why Charizard is not so great on competitive game doesn't make him bad in base or even idea, if just make him bad against what the people is currently using.
The games and the anime had always a different history, anyway, so, that doesn't matter too much, you can also see difference on the remakes and stuff. For end, I personally like the anime, I first started playing Red/Blue, and when I knew about the anime, I just feel enjoy, and actually, I liked a lot the anime, the firsts seasons are the better, but the current seasons are still pretty good, I like to watch Pokémon on the TV, so, I like the anime.
It's giving bad reputation because it's childish? And what matters about that? Mario is childish, too, and it doesn't have an anime now. Pokémon is aimed for being first played by kids, later those kids start to grow up, some forgot about the series, and others recover the love for it and keep playing it at 13, 15, 17, 19, 21, and more years, so, of course Pokémon and its anime are simple and childish! That's the idea behind all, if the anime where a sort of "META SCHOOL!!11!", I could just changed the channel when I was small, and I'm sure I could still changing the channel of a thing of that sort.
Pokémon is unpopular on middle-high schools? Yes, that's true, but that happens to everything you can imagine, and exactly the same happens to every thing that people offen start while they are kids, watching anime? Oh, no, that's a silly child's thing, let's bull that. Collecting figmas or similar? No, they looks like the toys I used to play with, bull that! Playing Mario/Star Fox/Any non-CoD-like-videogame? You're a stupid kid, let's bullying you hard! Why that happens? Simple, when people are at 13-18 years they offen doesn't know what is actually being an adult, but they want to being one, so, they tend to missunderstand the concept, and they think if they get far from what they played and stuff when they were kids they will "grow up", but that is not a fault from Pokémon, or actually, anything at all apart from our kinda pro-"adults" lame society, but that stop matters (at not total, but huge degree) once you enter to the - real - adult life (or at least you truly understand what is and what is not being an adult).
