I last had a TV in 2003. I do not miss it at all. Very occasionally a friend will report seeing something that sounds exceptional and then I wish there were some way of buying streaming access to that one thing. I particularly love powerful plays and period dramas, being a veteran of their golden age: roughtly 1960 - 1980. Most modern period dramas are hopeless as the dialogue, body language, etiquette & eye contact all reek of the 21st cetury.* But the old ones are mostly superb, e.g. The Six Wives of Henry VIII (Keith Michell), Elizabeth R (Glenda Jackson), I, Claudius (Derek Jacobi). I would so love re-runs of any of the long-running and challenging series Play for Today, The Wednesday Play, Armchair Theatre.
* An exception is Wolf Hall, which I thought was beautifully crafted and performed.
Up until roughly 2010 is when television began to lose me.
