First season was great when it originally aired, because it was so highly anticipated and about the only decent SF on the air at the time.
But it really has not aged well.

Show
The lighting and music for the first season have much more in common with TOS than with later seasons of TNG, so that can seem rather jarring.
And everyone is still finding their characters, so some episodes are quite goofy, occasionally on purpose. And the writing is often not great.
But if you can get through the first season, the show starts becoming truly great. I've been watching later episodes on BBC America and many of them hold up very well. And Guinan always steals every scene she's in.
