Martin Scoresqueezey’s review published on Letterboxd:
Spencer was weird...but not really in a good way. It's annoyingly awkward throughout, scattery and generally uninteresting. Visually displeasing, unless you're a fan of the "soap opera effect" style camera...(currently really tired and really stoned so don't take my word for it. Could be the ole peepers playing tricks on me). Lastly, not that I knew Princess Diana on a personal level... obviously...but I'm pretty sure she wasn't this out of wack.
