This is top notch X Files - a final season episode that puts everyone in danger and moves the story along well.
Scully's feelings are portrayed brilliantly - everything from distrust to belief and whatever in between. The thought of seeing Mulder again, and then nearly getting him killed.
Although the cast list shows 'Terry O'Quinn' as the Shadow Man, for some reason he chose to be listed as Terrance Quinn in the titles. Always a good actor and it's a bit bizarre seeing him in this episode of the X Files without thinking of him in Millennium, where 'Shadow Man' could just as easily have summed up his character.
It's frightening to think that every minute of our lives could be being watched and manipulated - maybe there's a conspiracy theory brewing there too!
Good to see the Super Soldier storyline moved on to a possible way of killing them.
