I think the main problem this series faced is the six episodes it was given, because my main gripe with it is how undeveloped all of its plotlines were. We had so many characters, all of them with their own storylines, and so it was only logical for none of them to get enough screen time as a result. It even happened with the couples, with which it felt like the romance developed randomly in a blink of an eye. We also had so many themes I wish we explored further, like Arthid and Sun apparently meeting as children, which was such a random five seconds input, or how Sun became friends with Arthid's buddies. Overall by the time the series ended, it felt like none of the plotlines were properly wrapped up, and I think the series would have benefited a lot from either being simply longer or just straight up cutting some plotlines and characters, 'cause the set up was far too elaborate to execute properly in six episodes.
That being said the shots of the island and the colouring were stunning and overall it was a very pleasing series visually.
