What is special about films from 1930's....

I knew once refreshed you would recall.

I can understand the appeal for many of the style of film that was released in the 30's, with being such a dark and bleak era. Film-making technology and the advent of sound were all new and that is why perhaps the Busby Berkley musicals were such a big thing as well. In hindsight though, I can see the naivety and embellishment in them as totally from a different era that I don't really care to relate too at all. There were top stars to come out of this era and they also lent their presence into the next few decades which was nice to see, but I can't just bring myself to gravitate towards this era, especially when there are other older films I would rather watch. It appears as Hollywood superficial at its most obnoxious.
