Netta's quirky, chicken noise-featuring winning song has certainly divided critics, while the prospect of Eurovision heading to troubled Israel in 2019 has also prompted much discussion online among fans.
"Thank you for choosing me. Thank you for celebrating diversity!"
The annual musical extravaganza has always been known for its ludicrous costumes, glitz and high-tech stage effects. "This year, the competition took place in the Portuguese capital of Lisbon for the first time in history of the event".
Barzilai's victory is the fourth time Israel has won the contest.
She received the Eurovision trophy from the last year's victor, Portugal's Salvador Sobral, who had called her song "horrible" in an interview published in Portuguese daily Publico on Wednesday.

Oh, and as if that isn't a big enough coincidence it's worth noting that Israel's first victory in the contest came in 1978 with A-Ba-Ni-Bi - exactly 20 years before Dana and 40 years before Netta. SuRie's performance was marred by an intruder who invaded the stage and grabbed SuRie's microphone during the song's closing moments.
The man got hold of the microphone but was quickly tackled by security and taken away while SuRie stood by.
Eurovision is staged by the public broadcasters that are members of the European Broadcasting Union, which stretches from western Europe to the Balkans and Russian Federation - and also includes Israel. SuRie was offered the chance to perform again, but declined.
"I am really excited, really happy", the 43-year-old, who wore a blue and white Israeli flag around his back, told AFP. All in all, a controversial year for the song contest.
Eurovision was first held in 1956 with the aim of uniting Europe after World War II.
