About
You’ll likely enjoy this if you want an intimate, often tender relationship drama about a polyamorous triad in London, similar in spirit to Feel Good; Not for you if you need fast plot turns or clear-cut answers.
Pros: warm chemistry; thoughtful relationship drama; strong performances | Cons: slow pacing; premise feels unlikely; focus sometimes drifts
