Some parents took to social media to criticize the action adventure series' 6:30 p.m. time slot though, citing violence and scary monsters.

U.K. TV giant ITV's first episode of action-adventure series Jekyll & Hyde on Saturday evening drew an average audience of 3.4 million viewers, according to overnight ratings data provided by the company.

The show peaked with 3.6 million viewers. tweeted that this included "higher than average shares for adults 16-24 and 25-34."

But the show also drew criticism on social media as parents said it included content for mature audiences, including violence and scary monsters, at 6:30 p.m. Under British TV rules, such content traditionally airs starting at 9 p.m.

Loosely based on Robert Louis Stevenson's book The Strange Case of Dr. Jekyll and Mr. Hyde, the 10-part series is written and executive produced by Charlie Higson.

The story is set in 1930s London during a time of "Hollywood glamor, aerodynamic cars and monster movies" and focuses on Robert Jekyll, the grandson of the original doctor, on a quest to discover the nature of his curse.

One viewer tweeted on Sunday that the show should get the "award for 'Most Unsuitable Time for a TV Program to Ever Be on'," while another said "This is not 6:30pm TV  ... It's great but hardly tea-time viewing."

ITV issued a warning before the show aired, advising parents that it included some violence and scenes that younger children may find scary. Said a spokeswoman: "ITV issued a warning before the transmission of Jekyll and Hyde advising the parents of younger children they may find some scenes scary."
