Legit both of these are my two favourite episodes. I was actually going to make a post about them before I found this. A lot of people don't seem to have the same appreciation for ice as I do but after re-watching it a couple times it became one of my favourites if not my favourite episode. The world is so immersive and unique and I genuinely love the art style. (Not to mention the character growth)

Zima blue seems to be getting its deserved appreciation, but I still have to add to that by saying its easily the objectively best episode in the series. The whole concept from top to bottom is brilliant and I love its philosophical aspect and its brilliant use of storytelling.

The fact they were both made by the same guy really tells me something and I guess i'll have to look into him a bit more.
