It's hard to recommend this show. I started watching because it was saint seiya but in truth it has little in common with the old show and I think fans of the original will have a harder time appreciating this.
Regardless I'm not surprised that the show has a low rating, because honestly the start is pretty weak. That said the latest episodes have improved MASSIVELY, and they even thrown a couple of twists, one in particular that I didn't see coming and was really not expecting from what the show had previously shown.
If it keeps this up it may well become a pretty good show instead of the mediocre one it was until recently. Time will tell.
