While it was amazing at the beginning, it started slowly getting bad.
Story:
The setting itself is intruduced in a rather rushed way, but showed a lot of potential. Sadly, it went down to a "which boy will Wako choose?" and "Takuto beats down the Kiraboshi" without very much development.
Art:
I don´t have much to complain here. It was a bit too colorful in my opinion, but especially in the fighing scenes, you could see were all the graphic-work went.
Sound:
The soundtrack was maybe one of the most outstanding features of the anime; the tracks themselves felt good, and the insert songs were a great addition.
Characters:
Here it stars going downhill.
Most characters hardly change from your first impression. From my point of view, exept the love-triangle centering Wako, there is almost no character development at all. Most of the female characters even fell in love with Takuto or Sugata to a certain extent, at the very least they didn´t see them as enemies anymore.
Enjoyment:
Takuto comes. Takuto fights. Takuto saves the day.
That´s basicly what every episode was about.
With the sole exeption of Head, most of the Kiraboshi-members somehow didn´t take their goal serious, beeing all nice to Takuto or even becoming his friends outside of the fights. Until shortly before the end, no one got at least once the idea to fight him with more than one Cybody. It seems that defeating/killing him outside of a Cybody was never an option either as well, since nobody tried even once.
At the end of the story, you hardly feel like anything important happened since episode 2, because there is hardly any new plot-related information at all (ignoring a bunch of other love-relationships).
Overall:
I really liked Star Driver when it started, then it became a single sided "Takuto ownez them with some new/old technique or help from Sugata" - business with a featured "girl in love" theme. More background to everything Cybody-releated might have helped alot.
