What I like about Nobunagun:
-NICE BATTLE!!!: there's a gun, there's a blade, there's a barrier, and other types weapon. and the enemy's power is their number, that is overwhelming, and their ability to evolve fast. oh, well... let me say that again... IT'S NICE!!!
-Nice characters: Sio and Jack (Adam). if you want to know what kind of people they are, you should watch the first battle, since I can't explain it. but, they have interesting personalities.
-Unique art: well, not really, just something like unique.
What I dislike:
-Some story of the earlier episodes. Actually, I like simple stories better, that's why, the not-so-simple story at the earlier episodes seems bad. and the other reasons is that they messed with the character, this could be my own preference. I don't hate the story itself, but I just dislike some of the stories at the earlier episodes.
Neutral:
-Sound: it's not bad, but, since the battle is good, I want it to be good too, so I imagined the best OST I ever heard when watching the battle.
-Other characters. I don't hate them, but, I don't like them as much as the other two above. well, this is just my preference.
