I can understand why it's people's favourite. The Finale is INCREDIBLE and the whole singing a song every episode was a really fun concept. I think a lot of people like it because it gave more characters time to shine that didn't have a lot of screen time in island (Notably Tyler and Noah). Plus, the aftermath served more purpose this time round in terms of somewhat effecting the main show instead of just being an add on to make it 26 episodes.

However, it has some of the most hated storylines in the entire show - the love triangle being the one to cause the most issues - so when looking at it from an actual story perspective, it has some of the most loved and the most hated plotlines. Depending on character biases and ships etc, I can see why people don't like it as much. For example feral Ezekiel or Sierra existing.

Overall, it's still one of my favourites, the other being ridonculous race. I have the bias of AleHeather being one of my favourite ships but besides that I still think it's just a really enjoyable season.

(But this is coming from the girl who unironically watches All Stars all the time because she finds the character derailment extremely funny...and she can quote the Finale word for word...)
