It was so bad that I lost all interest to ever try it on film body. On other hand, Nikkor SC 1.4/50 and Ais 1.4/50 are way better lenses.
Erm, the D7000 has a relatively high pixel density so of course it's going to exaggerate any flaws a 50-year-old lens might have. DSLRs don't always work well with ancient optics; My DSLR hates some of my old lenses but does fine with others of the same vintage.

Besides, the pleasantness of a lens' rendering is a highly personal matter. Your mileage may vary, as they say; simply calling a lens a dog because it's less sharp isn't fair.
