Let me state that I haven't read the manga nor am I an Ultraman fan, so my review is based only on the anime and aimed at those with no particular attachment to the Ultramanuniverse. I scored it a 7 basically for the good animation, character design, and action sequences. The series is really entertaining and fast passed. The fights have nice choreography and are visually astonishing. The scenes where the new Ultraman Taro (this is no spoiler, he is in the promotional banner) is the protagonist are highlights of the series and worthwhile watching by themself. On the negative side, the whole story, which spanned only6 episodes, feels really rushed. There are massive plotholes that are immediately evident to the viewer. It feels like there are at least another 4-5 episodes missing in between. Some characters appear out of nowhere and change the course of the plot just because. Definitive events are just reversed out of nowhere and without explanation, kind of ruining the experience of having an emotional investing moment that is totally meaningless 2 minutes later.

Overall, if you have seen the first season, I would recommend watching this one too... but be aware that you are going to have the feeling that this one is way too short in comparison. If you have read the manga.... then skip the anime.... don't watch it!! unless you are able to enjoy the animation without getting frustrated with how much it differs from the manga.
