good comedy, not good adaptation

I saw this in the theaters when it came out, and I was deceived, since I had been told it was a direct adaptation from Marc Lévy's novel "If Only It Were True." Definitely NOT an adaptation, but rather, the movie is anything but loosely based on the novel in the question, since many characters in the book differed from the movie (the mother is in the book, there is no sister; her dog, not her niece, "sees" Elizabeth; etc.), or they were added (the guy from the psychic/occult bookstore).
However, this is my second viewing of the film. I have put aside the fact that this is a film based on a book. And I actually enjoyed this comedy, a lot. So put the book's notes and story aside; watch the film for what it is: a good comedy, with lots of laughs and cute moments.
(Too bad there won't be a sequel to the movie [not with the ending the film had], as there was a sequel for the book: book#2 was simply the same thing, with the same characters, but the accident happened to David, oh my! how original.)
