I'm a bit lazy so I'm also doing this on behalf of the animated movie into this review, I know that's probably a bad idea or a wrong style but laziness. This was also the start of my admiration of Tomoaki Maeno when I had no idea who he was, the voice actor of our Doujou.
Story, I don't even remember or know how I gave this a try but I do remember the fact that this wasn't my usual style, especially with army/military theme or cliche. I was able to broaden up my taste of theme even more. Book burning, restriction, censoring, librarians defending back, media influence, by being a bit of a book/manga person I am, this cliche hit me right in the spot. Setting is realistic enough so it serves as an extra bonus.
Art, no biggy as usual.
Sound, the OP/ED songs were pretty easy going for me, the soundtracks were the same as well, I did enjoy it and it did keep the anime flowing decently so my 7's there.
Character, the heroine, our Iku, she pretty much joined because she was inspired and in a nutshell, wants to meet her man who protected her. She starts shaping up from her mistakes, and I quite like her personality in overall except that one scene where she almost rebelled against her mom. Our hero, I relate to this because seeing a "past version" of you, is very nostalgic in a bad sense especially if you want to get over it (lol). The rest of the characters were very good too, I don't want to go on with this, they're crucial to the series after all. This gets my 8 for sure.
Enjoyment, I definitely loved it with no regrets and rewatching is fun for me.
Overall, my usual routine is to only suggest to a general viewer, or unless I know someone who's taste might be similar to mine and or I can see a theme to their taste. I've enjoyed and love it, and it's short, realistic in a sense.
