Flannery O'Connor damned the novel with pretty faint praise when it came out: "I think for a child's book it does all right." That seems unduly harsh (and unfair to YA literature). What works best for me as an adult reader is the slow accretion of local color, the barbed social comedy, and the graceful prose.
Forever has a strong female lead, generally good scripts, and Gruffudd's opening and closing reflections are often thought-provoking. But I wonder if the fact that the show is based in fantasy has made the writers lose their grip on reality and decide that whatever they think needs to be real for the show is real.
There is statistical evidence showing that adult women read more novels than men, attend more book clubs than men, use libraries more than men, buy more books than men, take more creative writing courses than men, and probably write more works of fiction than men. If women suddenly stopped reading, the novel would nearly disappear.
