Sandman is another graphic novel series, this one by Neil Gaiman. It is very famous, and was so from the time it was first published in 1989. The Wikipedia page details it's history well.
Having recently read the Saga series, Sandman is quite different which probably colors my reaction to it. It is very dark and dense, using every bit of space on the page for either a lot of text or illustration. That's not a bad thing, it's just a very different style. Many of the pages seem busy, overwhelming the reader with detail. Panels are heavily used, appearing more like a comic strip in someways. Saga though would often use a whole page to tell a scene of the story instead, with sometimes very minimal, if no, text.
The story itself revolves around a character called the Sandman, or Dream or Morpheus depending on who is talking about him. No matter his name, he rules dreamland and makes it possible so that people can sleep and thus dream. However, the story starts with him being accidentally captured by a cult whose spell went wrong, leaving the whole world without proper sleep and dreams for around 70 years. The main plot meanders away from Sandman and covers various other people, making it difficult to connect with the main character since he is barely mentioned and focused on for quite some time in the first volume. In the second volume, he is the main focus but by then I felt but I was barely connected to him as a reader and so didn't care very much whether or not he reclaimed his kingdom and built dreamland back up again.
About halfway through the second volume, I put the graphic novel down and have it picked it up since. I just didn't feel connected to the story or compelled to read more. Having not read Gaiman before, I wanted to give Sandman a chance since it is a very popular, famous work of his. Compared with more modern graphic novels, it just didn't speak to me. I know that it means a lot to many people, I just think I picked it up too late.
Recommended?: To Neil Gaiman fans and anyone who loves classic graphic novels. For the most part, the content is just dark but there is some brutality and a side plotline of brutal violence in a diner that lasts for quite a while. This is another adult graphic novel, due to its violence and sophisticated story, which likely would be too high level, slower-paced, and philosophical for younger readers anyway.
