The Chase

This is a wonderful episode of Star Trek : TNG with a superbly 'Trek plot.

While most other reviews have focused on the main story element, I feel the need to point out that there is some excellent acting by the cast and guests (and some humorous moments provided by them)

The Message behind the plot is superbly played out in the final scene - Patrick Stewart's laconic replies are excellently delivered. Making for quite an emotive scene.

To summarise, It's a fun mystery, a good chase (you'd hope, given the title) and adds lore to the Trek universe.
