Undead Unluck probably has the most explosive and action-packed first few episodes I've seen all year. No surprises that the animation is probably the biggest highlight of this show, thanks to David Productions who have worked on a number of high-profile shows including Jojo's. The action scenes are reason enough to give this show a shot, even if you don't care for the plot, like I didn't at first. The Opening song and video for S1 are also really really good, one of my favorite openings of the year for sure.
The abilities of Nullifiers, the guys with powers in this show, are flashy and interesting in typical shonen fashion, with particular detail given to Andy's power of "UNdead". He not only cannot be killed, but he can turn his body parts into projectiles, detach and use his head like a bomb, can use a katana he keeps sheathed in his back...it's all SO stupid that if you struggle to suspend your disbelief I completely understand. The bombastic over-the-top nature might be too much for some, but the upside is that if this is the kind of thing you're into, you're going to really enjoy it, and it'll be very obvious right away if this show is for you.
And speaking of shonen cliches, the other main character, Fuko, is a cute shortstack who has a pretty decent amount of fan-service, which I'll admit can be a perfectly valid criticism of this show if that's something that bothers you. However the reason for the, let's just say gratuity of the fan-service, is done intentionally for plot reasons. I'm not really trying to excuse it or anything, but given that this show is just barely grounded in reality as it is, I feel comfortable just letting it pass.
And for godsakes, have you even SEEN Andy? Dude is the most jacked guy on Earth and he's naked in almost every scene he's in. And yet, none of this bothers me at all because it's so fun to watch. I'd actually consider Undead to be decently progressive given that it's offering something to both sexes, very cool stuff.
Like I said, I started watching it with the expectation of minimal or bad story and very good action, but I eventually discovered that there's a lot about the world of Undead Unluck that is hidden from us at first, and it's genuinely pretty captivating. The urge to see how things got to the way they are, or to see what we haven't seen yet is perfectly good incentive to look forward to the next episode. And that's to say nothing of the character development. I'm only on ep 9 but I feel like we've already seen both Fuko and Andy develop as characters in some really satisfying ways.
If you're into crazy action shonen and you're looking for a fresh take on the genre, I cannot recommend Undead enough, and like I said earlier, it's only going to get better from here.
