Early word is still building – the show has not yet accumulated a Rotten Tomatoes score or a widespread critical consensus. What exists is positive buzz from the network’s own press: Sky Group (official announcement) calls it a “sun-drenched thriller,” and first-look images released by Deadline (industry news outlet) in May 2025 generated interest. Viewer ratings on IMDb remain sparse.
What did viewers say about The Iris Affair?
- On Reddit, early discussion (Reddit (community discussion)) focused on the chemistry between Algar and Hollander.

“The script has the pace of a thriller but the heart of a character study. Tom and I had to find the exact point where trust breaks.”

“Cameron Beck is a man who has everything except control over one person – and that drives him mad.”
— Tom Hollander, during a Q&A hosted by Radio Times
