Ooh. Where to start. Well, I'm bad at writing reviews, so let's just start somewhere! Gakuen Senki Muryou.... is very interesting. Scratch that. AGH I just finished the series and I have so many questions! Anyway. Gakuen Senki Muryou has an interesting premise, and it has a mix of SciFi and Slice of Life. And lots of secrets. Aliens attack one day, or somewhere, while the main cast goes off to school and has their school shenanigans. It's a weird mix, but somehow it works. The sound. Well. This is from 2001. The songs were nice, I found some a little cheesy, but overall, totally enjoyed it. The voice acting isgreat, very good.

Characters are varied, all have their uses, personalities, most get some form of character development throughout the series, etc. And they're all important somehow! Most of the main cast gets at least one shining moment of awesomeness, where only they could save the day and they did.

When there's anything happening, there's either some very slow-paced plot development, or character development. Everything's useful in some way.

There's also a lot of perspective shifts, from the middle schoolers, to the adults, to the other adults, and to the aliens somewhere who-knows-where. It changes a lot, and they all talk about different pressing matters, but somehow it works together.

All I really want is some season two, or some answers, but seeing as it's been nearly 20 years since this aired, I doubt there'll be another one... But please. Answers. I need them ;(

(Although the plot pacing is pretty slow, it's a good story, though it seemed very rushed at the end. I'd still recommend, and as others have said, this is definitely some sort of hidden gem.)
