Why do lenses that would not be questioned on film, seem great on D200, suddenly get worse on D7000??
Is the answer to go back to the D200??!!

First of all, film and sensors are very different physical constructions and consequently respond differently to lenses (or the way light hits their surfaces).
The higher pixel density of the D7000 leads to a higher measurement frequency, where a lens might behave differently. In addition, many lenses struggle on the D7000 sensor to deliver very high border resolution figures. This may be a consequence of how the D7000 sensor is physically designed (in terms of AA-filter or micro-lens layout).
That alone, however, is hardly a valid reason to go back to the D200 (or the D80, if you want to keep the body size small).
