Quick-take: X-Files did not translate well in to a radio show.
This was not an audiobook. This was a radio show. Everything progressed through dialog, music, and audio effects. It was well-produced, but I did not enjoy it.
I found the series impossible to follow. Characters arrived and disappeared without introduction. I suppose Audible assumes we are already die-hard fans of X-Files and simply know everybody and their backstory by voice recognition alone. Perhaps I have a bit of Auditory Agnosia, but I would have really appreciated a few "Said Scully", "Said Mulder", "Said Smokingman" to help me.
The show was very episodic. Each chapter fit in to a neat TV-sized package. I am not impressed. A nice thing about books is not being bound to timing for commercial breaks. Perhaps these episodes were rejects to be back-fitted to this radio show?
I was surprised how much I did not enjoy being purely an outside observer. I like being deep in the mind of the main character. I like seeing the thought process. Knowing the internal struggle to make a decision.
Sometimes, a book would just "pause" for 15 minutes while the hero contemplated an important in-the-moment decision. That can't happen in this radio show. Everything is real time.
Needless to say, I did not buy season 2 of this production.
