I totally agree with you that animators who try to imitate the style of the '30s do things that are completely generic and stereotypical, and the result is all too often something that has absolutely nothing to do with the cartoons of that era.
The main reason why these animators fail so miserably is that they see the rubber-hose style as archaic and outdated, a few obviously untrue since it exudes life and modernity. What's more, if the Disney studios hadn't imposed a new, realistic animation method, rubber-hose animation would have continued to be used to this day.
Unfortunately, Disney imposed its way of animating on other American studios and then on studios worldwide, killing the rubber hose style for good, and needless to say, I hold a huge grudge against Walt Disney for that.
Today, Walt Disney fans take pleasure in belittling rubber-hose animation, as in
this article for example.
