Rusty definitely wasn't a good husband in the book or movie, but when I said "more sympathetic," I meant the book and movie provided more background information about his state of mind. To me, being a nerdy guy who had never had a hot girl interested in him certainly didn't justify cheating on your wife but that information did make it easier to see why Rusty found Carolyn hard to resist. Rusty in the series is just as bad, but I think the book and movies had a more interesting perspective.
