Yup. It’s very nearly 10 years since I’ve watched a film in “the cinema” (as we call it over here; for us, ‘theatres” are the places we don’t go to watch live drama). And for exactly the reasons you give: even when the place is kept perfectly clean, the “cinema” is a very uninviting experience, with some honourable exceptions. (I used to love the Rio in Dalston, when I lived near there.)
