Bit I am most looking forward to right now is the 3rd season trailer! Must. See. It.
Its my fav season of TNG
It is the peak of TNG due to the passing of the torch from the Roddenberry-era to the Berman-era producers. The transition from one team to the other happens in season 3 and it retains the best elements of both
Gradually from Season 4 onward the Berman producing team removes bit by bit elements of S1 & S2 until eventually there is not much left.... replaced with the lighting & direction of a daytime soap opera and musical score to match :P (ok, a bit harsh, but you get my drift)
I've always thought the overall quality stayed strong from S3-S6. But yeah, in terms of lighting and music, I agree S3 probably had the best combination of styles.
