My good friend point out this:

An another bad point in this season is that there wasn't any real introduction when new stuff was introduced. In the previous seasons when new stuff, like the water stars, the golden kingdom, obsidian, the black circle first appeared, we at least had a small explanation on what they werebut this time nothing! they haven't even explained what the infinite ocean in in the show!The only explanation was given in the season synopsis from the promos and licensing
