Euphoria: How Twitter reacted to that wild finale

HBO's Euphoria has concluded its debut season and triggered countless passionate reactions from fans online.

The controversial show has been criticised for how explicit it is, with an unflinching portrayal of teen drug use, violence and sex - including frequent uncensored footage of male genitalia.

In its debut episode, Euphoria featured a grown family man committing statutory rape with a 17-year-old trans girl after wooing her using the online name 'DominantDaddy'.

Zendaya leads the show's cast, which also includes Hunter Schafer, Jacob Elordi, Algee Smith and Sydney Sweeney.

Euphoria is streaming on Neon in New Zealand and has already been renewed for a second season set for broadcast in 2020.

This week, the eighth and final episode of season 1 aired, packed with revelations and a surprise musical performance from Zendaya that is winning acclaim on social media.

New Zealand filmmaker David Farrier tweeted that the season finale left him "stunned".

"Last episode of Euphoria has the most incredible ending to a season. It's on par emotionally with The Leftovers," he said.

Many fans are calling for Zendaya in particular to be recognised with awards for her performance.

"I don't know what just happened, but all I know is that Zendaya deserves an Emmy," said @bracefacebracey.

"Just give @Zendaya her f**king Emmy. Right here. Right now. #EuphoriaFinale #EuphoriaHBO," tweeted @EhisOsifo.

Other fans tweeted in dismay at having to wait several months before they can watch more Euphoria.

"Me after binge watching season 1 of Euphoria, then realising after the season finale I'll have to wait another year for season 2," tweeted @ajirixo with a gif of a woman crying.
