Speaking as somebody who just finished watching the X-Files for the first time ever this year, I have to say that the revival is almost a complete disaster.
My Struggle 1 was awful. Not only did it introduce one of the most moronic retcons ever (aliens not having much interaction with humanity at all, and most of their supposed crimes being the work of humans using stolen alien technology—despite the numerous aliens who've been on the show before), but it also had Mulder and Scully broken up for no good reason.
The rest of the season was mediocre at best (with the exception being Mulderand ScullyMeet the Were-Monster, which was a brilliant episode).
Then we got My Struggle 2, which was so bad, My Struggle 3 had to retcon it away as a vision. The explanation for CSM"s surrival makes no sense and it has the pointless return of Monica Reyes.
My Struggle 3 was not as bad as the previous 2, but it still wasn't very good. The editing was choppy, the voiceovers were terrible and has the stupid revelation regarding William's father (more on that later).
The rest of season 11 was a mixed bag. We had some good stuff (like The lost art of forehead sweat), and some bad stuff (like Rm9sbG93ZXJz)
Then we got My Struggle 4, which was worse than the other 3. Not only was it just a lazy rehash of previous ideas (the X-Files are AGAIN, CSM is killed AGAIN, Scully is pregnant with Mulder's child, AGAIN) but it feels like such an unsatisfying conclusion. This is probably going to be the last time we see Mulder and Scully on-screen, and this is how it ends? Lame.
Also, Scully's arc makes no sense. She spends all this time looking for William, just to let him go so she can go off and have a natural child with Mulder, even though she's 54 and barren? WTF!?
Also, John Doggett doesn't even get a mention (I know he was supposed to come back, but still).
Also, what was the point of bring back Monica Reyes? She barely got any screen-time and she just gets anti-climatically, shot in the head at the end. Was is really worth bringing her back, just to perform a character assasination on her?
Also, William is a complete jerk, I hate him
Also, the retcon revealing William was nothing but a product of CSM and an experiment that Scully just happended to carry in her womb for 9 months was just so mean spirited and needlessly cruel. It also makes season 9 even worse, because it makes the whole story of William feel pointless. Also it's just a lazy rehash (because they already did that plot with Emily).
When Fox announced that they had no plans for an X-Files season 12, I wept with joy. But knowing Chris, he'll find a way to make season 12. But that will hopefully not be for a long time, and hopefully by then, he would have come to his senses and write something good.
Personally, I consider season 8 the end of the X-Files. Mulder and Scully were together and could live normal lives, all the bad guys were dead, Kersh was going to be punished for being such an annoying character and it just felt like a perfect ending. Too bad Chris just doesn't know when to quit and just leave the X-Files alone.
Sorry for the long post, but I had to get this off my chest.
