Yeah their are some tweak too be made.
In a screwed up way, as bad as the US networks/blocks have been at points during this decade on how they've handled some series, they've also managed to give some creators fantastic runs where they've been fairly free to really express themselves. I mean, Cartoon Network and Nick both made some major gaffes this decade, but they also both put their weight behind titles that seem to have perennial appeal, and have nurtured as many amazing talents as they've squashed. I can scarcely think of good animation director from this decade that hasn't had the chance to at least work on a really good show, if not create a long running title or two themselves, and a lot of those shows were merched out pretty well too. They also often took the time to let a title find an audience and grow into itself such that it could be a real success, even when it might have been easier to kick people to the curb. If they hadn't, a lot more than just Invader Zim and Sheep in the Big city would've been canceled early.
In short, just as was the case for 1990's, the 2000's were a decade where American animators had the keys the asylum most of the time, and were left alone to run it barring some standarRAB and practices issues (and that changed dramatically with Adult Swim, as it opened the door for stuff like SuperJail and Aqua Teen Hunger Force - the audience which animation was being made for broadened significantly.) Japan, in contrast, feels like there was this run from about Evangelion through Ghost in the Shell: Stand Alone Complex 2nd GiG or maybe the first Haruhi series where creative work was getting the same attention as patently commercial work, especially when you add the rider the show not being a product of attempt to keep anime from losing diversity (IE: exempting Noitamina.) Past that point, the creative people are being squirrel away to work on extremely avant-guarde stuff, barring the occaisional good manga or light novel adaptation. In fact, there has been very little in the way of good stuff in the past half-decade or so that was done as an anime first. You have Michiko to Hatchin and Samurai Champloo, but I'm hard pressed to come up with another great anime original on the spot from the past 5 years that was very viable commercially. The other good originals as of late have been very weird and inaccessible, which iscool, but not necessarily helpful in a broad sense.
