Detour continues with the strong start that season five has. Mulder & Scully hit the deep woods again, searching for "invisible" creatures. Frank Spotnitz wrote this stand-alone episode by himself. He usually sticks to mythology episodes or writes stand-alones in a threesome. He borrows the concept of the story from the movie "Predator", but the story is still exciting and engaging. Frank Spotnitz is excellent with dialogue, and Mulder and Scully deliver some classic lines. He really has the Mulder/Scully chemistry down pat. In this episode, the boy is watching "The Invisible Man". You can always bet that any TV show or movie being watched in the x-files is related to the theme of the show somehow. They're not just random shows. The special effects of the chameleon-like moth men is very good. The only flaw in the episode hearkens back to the teaser when the two surveyors each see the moth men in the ground. It's a nice special effect of their faces in the ground, but if they are evolved humans like Mulder says, then they wouldn't be part of the ground, like it shows, but just blend in with it. And, the moth man just laid there, allowing the surveyor to stick a stake in him? If the teaser had been consistent with the rest of the episode, I would give Detour full marks. But, as it is, Detour still is an excellent episode, with wonderful Mulder/Scully moments.
