This series of stories was my introduction to Moon Knight in the 70's and 80's as he took the final pages of "Hulk" magazine. I remembered the essence of these stories, but it was in the re-reading that I realized why they stuck with me. This was Moon Knight beginning to figure out the whole split personality thing, and it was a gritty story (especially the part involving the axe murderer) that you didn't see in the regular comics back then. Reprinted here in glorious color and including the original covers from the Hulk magazine each story appeared in, you are given a real treat.
Though this story is very tame compared with the violence seen in today's comics, it should be noted this is better suited for a 18+ audience. No nudity, but it gets a little bloody at times. Also, this entire storyline appears in the "Essential Moon Knight Volume 1" paperback, which is cheaper than this and has more stories before and after it (though it's in black & white rather than in color like this collection). Unless you're a completest or just like this period of Moon Knight's history, you could buy the Essential book and get everything here except the color.
