The BBC's latest psychological thriller aired on Sunday night, with many viewers having high hopes after recent shows such as The Responder.
Chloe follows the unique character of Becky who compares herself to the picture-perfect lives on Instagram, but often finds herself returning to the same account.
Becky becomes obsessed with Chloe's social media account and clings on to their childhood friendship despite them not speaking to each other for 15 years.

But when Chloe dies suddenly, Becky’s need to find out how and why leads her to assume a new identity and engineer a "chance" meeting with Chloe’s best friend, Livia.
The first episode saw Becky begin an office job, covering for another woman while she goes on maternity leave.
Just minutes into the programme, viewers saw Becky steal a colleague's colourful coat, before sneaking into an event at the Royal West of England Academy of Art under a fake name.
Wearing the coat, Becky wandered around the gallery, gulping free champagne and eating canapes.
She then mingled with guests, pretending she was connected to the charity behind the event.
While there were many threads of the drama at play, some viewers were distracted - and wanted to know one thing.
Taking to Twitter, Elizabeth Daminger said: "Does anyone know where that coat is from?"
Belinda Green said: "Yeah I'm gonna need to know where that coat is from"
Razz70 said: "That coat.. Wow"
Andi5008 said: "What an absolutely fabulous coat"
Chloe airs Sundays at 9pm on BBC One
