I still think Tartaros was a terrible arc so watching it animated would be tantamount to extending your own torture. I did see some of the later episodes in that arc and they were, for the most part, awful. Not sure about those episodes leading into the Avatar arc though. If I were you, I would just watch Zero and skip the rest. That one had a pretty good adaptation overall.
