Good question. I really enjoyed "Broadway Melody of 1936", but it doesn't seem to get much attention. The original "Gold Diggers of 1929" also seems like it deserves more attention, but alas it is mostly a lost film. The clips of the finale that exist look quite spectacular, though.
I completely agree. Those two clips are a major disservice to the originals. The colorized clip of 42nd Street also has the entire brilliant street performance scene clipped out, skipping to the finale.
