As far as the shadowing goes, I like it far better than the flat, even lighting we got in later seasons where everything looks washed out. It gave the show a dramatic look.
100% agreed. The lighting used during season one is, by a country mile, the classiest and most stylish seen throughout the series. The over bright, and as you say, washed out appearance in later years, coupled with the "muzak", coated TNG with an unnecessary sheen of blandness.
