James Wong and Glen Morgan's follow-up to their excellent first effort "Squeeze" is middling, disappointing nonsense. The real issue with the episode isn't even the meandering plot (which will play to current audiences as "24" meets "Ghost Whisperer", and I don't mean that as a compliment), but the one-dimensional, annoying main character, and a poorly-acted one at that.
Wong and Morgan do get some fun humor into the episode, a nice break from the rest of it, which takes itself FAR too seriously given the subject matter. "The X-Files", regardless of what some indignant old-school fans might tell you, was always quick to mock itself through its characters, and only took itself completely seriously when it had a damn good dramatic story to tell. "Shadows" takes itself too seriously in any scene not involving Mulder or Scully, AND it's completely ridiculous.
In addition, the episode is hopelessly cheesy all the way through, and particularly the acting from much of the supporting cast, not that they're given any good characterization or dialogue to work with.
Meh.
