S04E04: Unruhe
OK, now we're finally getting somewhere. Cameras that take photos of people screaming in a vague headspace, a loony who is kidnapping women and get rid of the 'howlers' in their heads by poorly lobotomising them, and a chance for Scully and Mulder to again fall into a situation where one of them is about to die, and the other has to rescue them.
The concept of the camera that photographs the 'future' and this being the premise behind the action is a reasonable one, and certainly stills gets me in from the start of the episode to its conclusion. One of the more enjoyable episodes of season four. 4/5.
