Replace with a projector :) you don’t watch OTA channels, do you? So any other media source should be hookable to a projector. Sure you need a dark room to watch stuff, but that’s a plus as it’ll induce you to watch less tv ;)

Also - the soap opera thing can be turned off in decent newer TVs and as discussed in other HN threads you can just deny the TV an internet connection so it behaves dumbly. You might still need to contend with clunky UI but really - just select your video source and start watching, so the pain is minimal.
