I no longer follow any franchises, directors, writers etc. religiously, nor am I good about keeping abreast of new developments (probably the closest I get is irregular visits to The AV Club), but I am fond of quite a few ...
Perhaps my most confident base of media knowledge would be in the realm of Monty Python. That extends in particular to the post-Python work of Terry Gilliam as well as a good deal of 'British comedy' before (not movie- or TV-relevant) and since (The Two Ronnies, Not the 9 O'Clock News, The Young Ones, Black[ A]dder, Red Dwarf, French & Saunders, Fry & Laurie, AbFab, Bottom, The New Statesman ...)
The oldest U.S. shows that I've made any effort to collect so far are SOAP and Barney Miller, though I'll be catching up on Star Trek tOS on Netflix shortly. I ignored almost all TV in the '90s but have since learned to enjoy binge-watches of Firefly, LOST, The West Wing and various others. Latest favorite series is probably a toss-up between Sense8 and The Expanse; also generally try to keep up with Sherlock, Gotham, Game of Thrones, Agents of SHIELD and a few others.
With movies it gets a bit more vague. No studio loyalty; not fanatical about any period/style; around the top of several long lists of favored artists' work (entirely discrete from personalities and/or politics and/or criminal guilt) would be Kubrick, Soderbergh, Jarmusch, Fincher, Polanski, Wes Anderson, the Coen brothers, Spike Lee, Ridley and Tony (but mostly Ridley) Scott, Jodie Foster, Penny Marshall, Agnieszka Holland, Cate Blanchett, Tilda Swinton, Uma Thurman, Jackie Chan, Gary Oldman, Hugh Laurie, Tim Roth, Chiwetel Ejiofor, Patrick Stewart, Paul Newman, Sigourney Weaver, Max von Sydow, Donald Sutherland, and I'll stop for now with Robin Williams.
