I believe the main reason for the failure of the Weimar Republic was that most people actually didn't want a democracy. Right-leaning people saw it as a decadent and weak form of government and wanted the monarchy back, and left-leaning ones were split between a dozen different brands of communism or anarchism.

And of course it didn't help that previous military leaders had been worthless cowards who continued a losing war to a point where they could not longer sue for peace, then leave it to the newly formed democratic government to accept the onerous conditions imposed by the opponents and end up getting blamed for something they had neither caused not any choice in.
