No, it really is. Right from the time Tezuka founded his studio, anime has been about doing as much with as little money in as short a time as possible. They use every trick in the book (which they wrote) to make it look good without truly being "good" animation (though the art might be good, it doesn't count as good animation if it doesn't *move*).
Movies and long-release OVAs can be an exception because of longer production times but weekly shows? They have production schedules that make animators bleed and it's not exactly work that pays well, so you never know what you're going to get. Because the schedules are so tight, they have to go with what they have and any real fixes have to wait until home video release.
