I don't think it makes sense at all if you didn't watch the cartoon.

I had this exact thought after I finished episode 4 (my current place). While I am impressed by the technical aspects of the show, the pacing and exposition is poor and depends entirely on the audience already knowing what's happening in order keep up. And that's entirely putting aside specific plot issues.

There's simultaneously too much and too little happening. The Bumi, Mechanist, and Jet stories are happening at the same time (too much) but separately, instead of one at a time, and Team Avatar experiencing them together (too little team development).
