The series doesn't bring a lot of originality to the table, between an over powered protagonist attempting to defend another OP female character (who then become friends..) to harem fan service in the 1st season, its packed full of cliches.
But for all of that it's still watchable.
Pros:
- There is a second season.
- Good opening/closing music and score.
- Above average English dubbing.
- Consistent and good animation quality (1st Season).
- Mad Science, AI's and semi-sentient weapons.
- Japanese style combining robots.
- Some additional good scores in the 2nd season.
Cons:
- "Fan Service" inside the first few minutes.
- Trope heavy.
- High cheese factor.
- "Fan Service" heavy.
- Generic Harem subplot.
- Catgirls, don't mind them, just want an explanation in a primarily vanilla world.
- Small drop in animation quality in the 2nd Season.
- Neon added toT-Shirts, cars, planes etc. somehow make them "magical".
- Last third of the 2nd season was very weak with unresolved plot points.
