PICARD season 3 actually felt like Star Trek again.
By doing exactly what other seasons of NuTrek have done.
Professional characters
They disobeyed orders and essentially hijacked a ship to rescue an old girlfriend. Very professional
dialog that doesn't sound like some CW show
You had the seemingly main villian practically twirling a mustache throughout half the season while Riker and Worf make yuk yuk jokes.
several new ideas
If by new ideas, you mean ripping off scenes from other Trek products while bringing back the same tired old villian we've already seen too many times?
Plus it managed to work with the baggage of season 1.
by eliminating most of the cast of the previous seasons
