"Where Silence Has Lease" is the best TNG episode, of the first 2 seasons.
Q Who is my second favorite, and Measure of a Man third.
ST09 is the best Trek movie since Undiscovered Country IMO. Into Darkness is nowhere near as good, but still a fun movie. The TNG movies, with the exception of First Contact, are the lowest of the low points in the franchise. Nemesis and Generations are borderline disgusting.
In general, Trek has never worked well as movies, compared to the tv shows.
