Jinki Extend would have worked better as a longer anime, or one with two seasons. there are two storylines- one starring Aoba, and the other one starring Akao. Chronologically, Aoba's arc occurs before Akao's, but the anime shows them both at the same time, making it quite confusing. To save you the trouble, if there's a flashy scene transition it's probably going to shift from one arc to the other.
This showing of two arcs at the same time is not a good idea-the show gave us a lot of time in the first half with Aoba, then it suddenly shifts into focus into Akao in the latter part. However since you have not been given time to "bond" with this new cast, you may not care for them as much.
The mecha design is okay-nothing stands out, really. Music is very good- it gets you pumped up for the battles. Especially in the Akao arc, with it's city setting. Expect lots of collateral damage.
Overall however it's not too bad- I still enjoyed the series, especially near the end since both storylines merged and we get too see characters from both arcs fight together, which was great.
This would have been better if it had two arcs-or at least, if it showed everything in chronological order. As it stands it's just an average anime-still enjoyable, but don't expect it to be really good.
