Meanwhile Xfiles has a montage on YouTube of all the times the boom mic crept into the shot.
So I can’t super accept that these are geniuses - it was cheap TV.
In hindsight sure, whole cult following etc. but doesn’t mean it is well designed or even thought out.
What does the writing quality, genius or otherwise, have to do with the boom mic though?
Bugger all - particularly given the boom mic operator and other framing "gaffs" are (as I recall) all part of the "wide screen" 16:9 later release on BluRay etc that were somewhat rushed out the door.
A number of shows of that era were filmed wide (16:9) and post processed / coloured / reframed and broadcast on TV in a box 4:3 aspect ratio
No visible boom mic operators, etc - careful eyes in the initial post production for TV phase saw to that.
Later wide screen releases were rushed with no real post production budget to address these and other issues - that's on the studios wanting a second grab at money, not the original creative teams.
Similar complaints abound for Buffy the Vampire Slayer and (IIRC) The Wire (?) and their wide screen releases.
There's a famous example of this in Malcolm in the Middle where the camera cuts to a different shot and a stand-in for Dewey is visible in the 16:9 release, but was not visible in the original 4:3 broadcast. So in one shot you have Dewey's normal actor, then in the next there is some random kid.
A recent similar example was Mad Men rerelease in 4k where the VFX weren't redone properly after a rescan of the film and you can see the man operating the machine with the pipe that spews sick out of a characters mouth.
