For me, I think it has to be Pulp Fiction. I just recently rewatched it for the umpteenth time and it’s just as great as ever. I find myself quoting it quite often.
A bit of an outsider which is a big hit in my family is “A Good Year” by Ridley Scott, staring Russel Crowe. It’s a nice fun movie and for a family of francophiles like mine it’s a great way of getting a bit of the France we love in the middle of the dark Northern European winter.
Sorry, new?! Unless this is something different from what I’m imagining, thermostatic shower valves have pretty much been the standard in Denmark for all of my life. You can get them for 80 usd (or probably even lower). These are purely mechanical, no need for batteries. I can even find one on US Amazon for around 50 usd (https://www.amazon.com/Bathroom-Thermostatic-Showering-Temperature-Control/dp/B071ZP4ZHN/ref=ex_alt_wg_m?_encoding=UTF8&pd_rd_i=B071ZP4ZHN&psc=1&pd_rd_w=MLPp3&pf_rd_p=e06954f1-ab26-49e7-940f-21fea3d5decd&pf_rd_r=1YGK573NBS6VC329GYD0&pd_rd_wg=PC4iL&pd_rd_r=4415efd7-7117-45ad-8b60-0a1c86e84ef0&content-id=amzn1.sym.e06954f1-ab26-49e7-940f-21fea3d5decd).
Edit: I realise that this sounded more aggressive than it meant it to. I was simply quite surprised! :)
I had an Nokia, my last “featurephone” before I got my first smartphone, which actually had an FM tuner built-in. It used the headphone wire as an antenna as far as I recall. Quite neat, not that I ever really used it, but it was perfectly serviceable. And a great way of having music on the go in the days before streaming music was widely available.
