Pretty Underrated, dont know why there is alot of negative reviews its pretty solid.
Art - 8/10 The animation is really good for the time, the effects are above average. But the animation is very stuck in its time. It isn't "Bad" But that time had probably the worst animation, it doesnt feel classic and doesnt feel modern so it just sits in the middle.
Characters - 8/10 Enemies are sweet, Main characters are sweet, no characters suck. A Pretty solid cast overall.
Story - 9/10 Even though i havent seen code geass it reminds me of it, could rip from it a little but does it realllyyy well. The story has moments where too much happens and moments where it takes its time and really cooks.
OST/Sound Design - 10/10 Holy shit the soundtrack is amazing, music really enhances the whole show. Sound effects are um very nice to the ears you could say.
Enjoyment - 8/10 Sometimes is a bit too slow, and repetitive but overall was really good, and an underrated show.
Overall - 8/10 really enjoyed this, wouldnt call it a must watch, but give it a watch if you have free time and wanna see some nice jiggle physics.
