Great quality. Great collectable
Came undamaged great quality put it up on a shelf next to my steelbook version of season 1 glad I got it. This show is so great. Owning a great quality version of it physically I'm so happy about. I should note I don't plan on taking out of the plastic shrink wrap it comes in. These in my opinion are great collectables so not opening either season. If I want to watch Ill just watch it again on netflix.

Season two is a fantastic addition to season one as another demo worthy picture.
Arcane League of Legends is one of my favorite animated series that originally aired on Netflix. It looked great on Netflix in 4K HDR. I initially purchased season one of this series on Blu-ray 4K and it is one of the best looking Blu-rays I have ever seen. It is demo material to show off my Sony OLED. So when season two became available I immediately jumped on the pre-order. I was not disappointed in season two looks as good as season one in this 4K Blu-ray. Once again it is demo material worthy. And while both seasons looked very good on Netflix, these 4K Blu-rays take it to a whole other level.
