yup, and it is nearly over already
You can definitely tell the difference. They have gone back to the tone and feel of season 1 and 2 and it has the added benefit of the increased production budget from Amazon. It is those lovely little touches like them drinking the bubbles of floating water that do it for my realism factor. It is supposed to be an inconsequential moment that doesn't affect the story but it serves to reinforce the underlying foundation of the universe.
