Most people are familiar with the importance of "The Death of Superman" - how it became a best-seller that made the news all over the world; how it began the trend of killing off super-heroes to boost sales and attention towards comics; so I wont bother to elaborate on it, as many reviwers have done so already. So I won't dwell on that, but give my opinion on the story, and adress some of the negative criticism it often gets.
I rather enjoyed it. It feels as important as intended, and its a riveting read. The artwork is good for the period it was produced in (early 90's). The sense of danger gradually escalates, and it does have the necessary tension to make it a worthwhile read. There are also some heartfelt moments, and it properly conveys the feeling of despair and exhaustion that Superman feels throughout. It also adresses the public's reaction to what is happenning in a slight, but effective manner.
"The Death of Superman" is often negatively appraised by alot of comic book fans.
One frequent criticism is that it consists of mainly one long fight. While there is some truth to that, it does escalate gradually, and several characters are involved, so I did not find it dull, repetitive or lifeless. Oddly, I've heard such criticism from people who love Sinestro Corp Wars, or Blackest Nigth, and those books also consist of one big fight. At least, in "Death of Superman", that fight feels like it has alot of stakes, and its well paced.
Another frequent criticism is the claim that, considering what Superman has faced before, a mindless brute whose only thougth and motive is destruction shoudn't be able to defeat Superman, a very powerfull, but above all, intelligent individual. I say it makes perfect sense. There is no reasoning with Doomsday, or time to plan much of anything, as he continuously goes through a destrutive senseless rampage, giving no quarter or chance to allow for planning. How can you plan for someone who doesn't have any objective, and relentlessly destructs and takes lives uncessantly, which requires a complete focus and presence on the battle? He has nothing to lose or gain, just destroys for pleasure.
The story is also critisized for being a cash-grab. Yes, it intended to garner attention and boost sales, and it did. But there is a clear effort on recounting that event in an engaging manner, and from multiple prespectives, despite the storytelling limitations enabled by what essentially one long battle. Visually, there is also some creative techniques employed (for example, the last three issues gradually decrease the number of panels per page -from three, then to two, and in the final issue, to one panel per page). So, you can see some though went into this, when it could have been half-assed.
And as for the complaint that it started a trend of killing off heroes? While that may be true, that's hardly on the book - it was the first of its kind, and made bank. So its expected that others of the same type would come about. But since I find the story very enjoyable, and it did break new ground, whatever it may have spawned doesnt strip away the value it had at the time of his release, or that it remains a good read.
I'd say its definetly worth a read, not only because of its importance, but also due to it being an engaging and well-written book. While some readers loathe it, its mostly a celebrated book, so its likely most people will enjoy it, should they give it a try.
