Spoiler alert (do not read if you have not yet read the novel and are planning on doing so):
I found that Audrey Niffenegger really captures the irony of Henry's time travel, as it all at once saves him from a life of misery and simultaneously leads him to his death. If his time traveling adventures had never led him to Clare, he may have remained a womanizing alcoholic. However, his time with Clare as she grew up saved him from his what seemed to be inescapable demise. On the same note, Henry's time travel leads him to an untimely death, stripping him of the possibility of growing old with Clare and watching his daughter grow up. Henry's time traveling ability is the silver lining of his life, as it both saves him and destroys him. I also love the ending of the novel when Clare and Henry reunite at the end of Clare's life. It seems fitting that he should time travel to the end of her life because although he tells her not to wait for him, it is clear by her reaction that she has done exactly that since his death. I found this story extremely compelling and emotionally engaging. Although I have mixed feelings about seeing the film (I find novels adapted to film are always hit or miss), I do look forward to watching the story on screen.
