I am sorry but I'm baffled by some of the negative reviews. I want to contrast it with The Walking Dead which is seen as the greatest zombie series.

All of Us Are Dead is very addictive. Makes you feel claustrophobic in the best possible way. The fear factor of the zombies retained throughout the series. It wasn't like The Walking Dead where zombies merely walk and are treated like jokes.

Another way it wasn't like The Walking Dead is that there is never a dull moment on this show. They keep the plot moving and don't spend too much time in sub-plots away from the main scenes. The formula was just perfect.

Yet another way it wasn't like The Walking Dead is that on this show, they didn't turn it into a political game of humans vs humans. It remained loyal to its gripping core, a zombie survival series.

I never watch K dramas set in High Schools, but this was just brilliant.

I wish there's a Season 2 and they stay loyal to their current winning formula.
