Eh, It was ok to be honest...the premise was already at fault considering it was missing both Extra and Unlimited, that are in my opinion necessary to fully enjoy and also understand some plot points.
Some others were indeed rushed/skipped completely, like the exam on the island, but again I can understand the reason for doing so, considering that the most important part of it was in Unlimited. Still, it would have been fair to have at least mentioned the vehicle there, considering it will have some meaning for a future character..
The main problem is that the girls have little meaning to be there, the main focus in the protagonist, and the rest look a lot like background characters, while they should all be the heroines of the show...feels bad seeing Ayamine treated like that...
Also, no "I'll choke you to death with my uguu" Easter egg...missed opportunity
