I think the rating becomes more and more difficult as we see several developments. Huge, heavy, fast, high-performance lenses might be just the right thing for a job with high expectations of resolution and lack of optical flaws.
Compact, easy to transport might be another need.
How to rate AF - it's not important resolutionwise (which is a big part of the rating) but after all, if the sharpness has to be adjusted manually to a given focal pane, a couple of subjects become impossible to shoot.
One might be happy with a "robust enough" design, for some other person maximum rigidity, waterproof construction (not the useless marketing blurb "weather proof") is necessary.
It's difficult to rate - if there's enough choice, the ratings might help to find some candidates quickly. If there's only one lens (at a given time there was just one 105/1.4, soon we could choose out of three) - how to rate it?
What influence to the rating if one lens doesn't reach the top of resolution. but widthstands flares more than the others? And what to do with ratings which were okay at their time, but these days are surpassed by other lenses? At some point the rater will run out of stars...
