I finally got to read Slaughterhouse-Five after reading a comment to Time Traveler's Wife that it was a rewriting of Vonnegut. It was something I wanted to do for a long time and I wasn't disappointed in the least.
It is a great novel with many motives and a strong anti-war message. It gives a great insight into mind of a warrior seen too much. The only reason I gave it 4 stars is that I previously read Catch 22 and it sometimes reminded me of that novel.
I liked the repetition of "So it goes" - there is a pre-echo of "Valar morghulis" in it.
And Time Traveler's Wife has nothing in common with it apart from time travel.
