SLIGHT Spoilers, arc name's are just mentioned pretty much

The art is pretty much it's only real virtue, it's incredibly weak in every other area.

The gore is very well done. That's what I originally read it for, though my enjoyment of that even started to dwindle as it was just the same junk over and over again. Shock for the sake of shock isn't good, especially if you try to shoehorn a plot into it.

Speaking of plot, Deadtube's plot is pitiful. I was fooled in the first chapters into thinking that this would be interesting, but it quickly fell apart after the Betsuki-sensei arc, and that's also the last time in my opinion that the gore was interesting. The Rascal arc was alright, and it went downhill after that. Unfortunately in the "Gore Community" I'll call it, there are a lot of edgy people, and that's all they care about. Edge. Deadtube is the epitome of that. It relies too much on nudity, gore, and other "edgy" themes.

Good characters are often killed off so you'll be stuck with tardihiro and his edge crew for most of the manga.

Overall, it's pretty bad, aside from the art. It had potential, but it quickly went to waste.
