Rather odd, yet just narrowly works... I think.
The performances of Jenna Ortega and Martin Freeman are two that I found entertaining. I'm usually nonplussed by the latter actor, I tend to find him quite mid in terms of acting but this is probably the most I've enjoyed him throughout the entire run time of a movie; he has better roles, sure, but purely on his delivery etc. this is a good showing of his.
'Miller’s Girl' does deliver a strange story, one that does feel quite amateurly written and one that's deseprate to be salacious. For an "erotic thriller", it doesn't really show all that much - if, admittedly, that's for the best in this regard. I will say, though, that Ortega and Freeman play it all off well enough though, which is probably why I didn't hate it.
I'm not surprised to see it tank on Letterboxd, even if I'm evidently not someone who feels as negatively as a load of others do about this 2024 flick. I do tend to give movies with good performances a pass as they can mask any other misgivings, so that ought to explain it.
