As noted, the hairstyles in the first two seasons of TNG are very '80s -- big hair ruled! -- but around season three, it achieved a less dated look. One thing I never liked about the bridge was the tactical station -- all that wasted space and it was the only station where you had to stand. I always thought tactical should be where ops is, that ops should have been where Troi was, and Riker should have had a "master console" next to his station, the way they eventually added that to the first officer's station on the Enteprise-E. -- RR
TNG does look dated (especially the first couple of seasons). Even more than all the other series. But I can enjoy it nonetheless.
