Is there an easy/elegant way of showing that "squaring" the Dirac equation in curved spacetime yields the Klein-Gordon equation, just like it happens in Minkowski space? A brute force approach would require a lot of tedious algebra dealing with the spin connection, the veilbein formalism and the Dirac matrices.
