It is weird to read about tv show fans bashing anime with a stick or a bat or whatever. The VAST majority of TV shows that are of a serialized nature are so far removed from the basics of storytelling that it is not even funny. They take the basics of what it takes to tell an engaging story (or a drama, more importantly), and they just twist the rules around midseason breaks, episode endings, season finales, cancellations and whatnot.
The only hurdle anime adaptations had to sometimes endure was when a studio needed to "guess" the outcome (or even make up a new one, sometimes with direct consultation in the manga's creator). So while the serialized nature of the beast is only present with long, monthly/weekly manga adaptations, it is the norm in the TV shows. Quite the different outlook, is not it? So yeah, when a book's american adaptation shocks viewers with killing tons of characters - that was not supposed to happen if they were out looking for the most popular cast, trying to keep that up for high view count )-, that is a glimpse, just a tiny bit of glimpse of REAL storytelling.
That being said, I still have huge respect for the writers for any long ongoing shows for being capable of even planning ahead more than half seasons. Now, where was I...oh yes, anime.
Full Metal Alchemist: Brotherhood. Show me the equivalent of that. Well thought out, has a diverse cast with people FULL of proper goals, motivations, issues and personal problems to resolve. It has plenty of good twists, drama, deaths, it does not go on longer than it is supposed to, and it makes sense all the way till the very end. Turn the discussion around, show me the US equivalent of that. A show that knows when to go out, one that does not get twisted by rating changes and schedule problems, where the main characters do not get hanging in the air like a broken thread of events like Supernatural's Winchester boys have been doing for what...5 years now?
There are plenty of great shows in both ends of the spectrum, and that is what matters. What I am arguing is that the approach to storytelling is, for the vast majority of anime/american television is *fundamentally* different.
