This is definitely the X-files you grew up with, in both the good and the bad.
The Good: All the people are exactly like I remember and are voiced by the actors who played them in the series. David Duchovny, Gillian Anderson and all the others do an excellent job voicing their parts. The same tensions exist and the same personalities, etc.
The book itself reads (or in this case sounds) exactly like the series. The writing is entertaining, and has the same feeling. It is like they just took up where they left off more than ten years ago. I do find this partially good and partially bad.
The Bad: The bad mostly falls into personal likes and dislikes. There is one single technical issue I disliked though, that would be the environmental sounds. It seemed very much on an audio stage and not sounding like it was filmed in an actual place. The echoes were off, there were seemingly missing ambience sounds.
This might just be a personal preference though, I haven’t heard a single audiobook who approaches it with multiple actors and using sounds instead of reading descriptions that has worked for me.
I stopped watching the X-files religiously as the seasons went on, especially the last season or two of Mulder and Scully (and I didn’t really watch it after they left). Not because there was anything technically bad about the acting or writing, but because I was tired of aliens.
The height of the show for me was when it was a “monster of the week” show with some plotlines that ran through the whole show. I didn’t even mind some of the alien/black virus/black eyes situation.
However, I stopped watching when it became all about a single government conspiracy with all knowing bad guys responsible for all the different things. I would have been ok if it was scattered conspiracy, but an all knowing invasion of aliens, followed with movies that only followed the same was frustrating.
This book does the exact same thing. There is one “episode” that deals with a monster of the week type situation (revisiting one of my favorite episodes) and it was great, the remaining episodes were very much one long alien conspiracy hunt. I won’t say anymore, I just want that out there to warn others if they don’t want to have to deal with it.
Overall though it was worth it, I got it on sale and I did mildly enjoy it. I will probably try any other book that comes out in the series, but I would rather it be done in a novelized/audible format and not that multi-actor/fake sounds setup.
