I've listened to the first two episodes now, and it's quite good! Everyone really knows what they're talking about, so you've got a strong foundation. I also really like the idea of this survey approach leading to the new season.
Highlight from episode 1: One of your guests describing what it meant to her watching Scully as a 13-year-old girl. I hadn't particularly thought about what a powerful role model Scully must have been, especially in the 90s. I had heard that, but I guess it hadn't really sunk in until I heard this story (and I wish she would have elaborated).
Highlight from episode 2: Grilling your guests with that brutal quiz. The spirited defense of Dogget and Reyes... a good counterpoint to Kumail Nanjiani's opinion (which I guess he hasn't fleshed out yet, but still). Not sure how to feel yet myself, since I haven't really rewatched the later seasons. Also in this episode, lots of assorted Scully insight. Plus your guests seem to get a lot more comfortable with the format, so that makes it go quite smoothly.
In case you want suggestions... I think the only way you can improve it as a host is either through editing or being more aggressive about steering your guests, which I can see being awkward. I don't know what your setup is technically, but being able to see each other always makes a podcast sound more like a natural conversation, especially when more than 2 people are involved. Because you get those visual cues that someone is about to start talking or has something to say. So you could try Skype with video. Anyway this is why podcasts or radio shows with guests that are physically in the room with their hosts always have the advantage. I think this is how very dense podcasts where people even actively interrupt each other, like How Did This Get Made or The Flop House, still sound so good, because everyone is friends and in the same room.
