Any Columbo film. I love Columbo, but i always fall asleep, shortly after it's been established who the killer is, then waking up just before Columbo solves the case. Last week we went to watch Glass Onion, and I very nearly had a little snooze in the middle section of that. Very enjoyable film, though.
I’m ashamed to say most arthouse films send me to sleep after the first 5 mins - non-emotive acting, bland lighting, scenes moving so slow they can barely crawl. Don’t get me wrong, in days gone by I’d love a good Bresson or Fassbinder (although some arthouse films today are genuinely shite!). Having said that, my concentration levels after working all day combined with illness related fatigue means even a Hollywood disaster film has me nodding off while periodically waking up with a start to the sound of gunshots, explosions or people screaming.
I tend not to watch films much now because I find most films boring (largely because I’ve probably seen 90% of the good films available to watch and watching them for possibly the 2nd or 3rd time).
I’ve been falling asleep through some of the more boring WC matches too - notably USA v ENG, ECU v QAT, and CMR v BRA - so that probably doesn’t say much about my ability to stay awake these days while watching anything.
