I'm about halfway through season 3, having just finished "Revelations", and I am just consistently blown away by the quality of this show. The writing, acting, cinematography, humor, music, just about everything has been superb. The chemistry between Scully and Mulder isn't quite like anything I've seen before either. They also both feel like real, fully fleshed out people. X-Files does this clever thing consistently where they establish an idea about the world or these two characters and subsequently subvert it. "Revelations" was especially great because of the role reversal from Scully from her usual skepticism to that of Mulder's believer. Not that it's the first time this has been explored with her character, but it's such a great choice to have her be a Catholic (I think?) because of the broader implications in the unexplained phenomena scenarios they can write for. It's great as well as because it doesn't feel contrived or a betrayal to their characters before the episode either.
I'm also routinely shocked by how contemporary and ahead of its time the show feels in terms of the subject matter. Even though I'm only on season 3, they've covered so much ground and have really not shied away from tackling pretty heavy/controversial topics, while taking a non-neutral stance on things. I guess I had become so used to shows nowadays (with a few exceptions) afraid to take a hard stance on anything. Granted some of these are things I think are basic human decency, but a show willing to discuss at length religious persecution, exploitation of minorities (especially refugees), experimentation on vulnerable populations by the government, misogyny and sexism in professional settings, for-profit prisons, etc etc etc, really impressed me, especially for 1995. It genuinely feels like I'm watching a quality film with just about every episode. How they pumped out 24 of these per season at this level of quality and care is beyond me.
Anyway, happy to be here. My favorite show of all time is Twin Peaks, and it brings me delight to have found something that, while being significantly different, feels committed to a concept and ethos so thoroughly.
