The Great Gatsby is brilliant, and the problem with Lord of the Rings is that you've all left it too late in life to try it.
Some examples of "Emperor's New Clothes" books for me:
Norwegian Wood by Haruki Murakami: Just duuuuuulllll, with endless descriptions of what people are eating, and a thoroughly unengaging narrator.
Paris Trance by Geoff Dyer: a trite load of crap about a bunch of wankers poncing around Paris and doing drugs and having anal sex to show what an Adult Novel they are in. People I respect love this book. They are MAD.
Most book I give 50 pages these days before I decide to throw them.
Agree about Time-Traveller's Wife - 50 pages, plonk.
That Lewycka woman and her sodding tractors - 50 pages, plonk.
And Virginia Sodding Woolf, oh Jesus H Christ spare me. Plonk.
Something which was recommended to me ages ago called Don't Ask Me Why by Tania Kindersley. This person actually thought I'd enjoy it. Full of smug Oxford stereotypes, swanning around being so thoroughly unlikeable that you really hope they are going to get hit by a bike and end up in the Cherwell. There is a great novel waiting to be written about what 80s life at Oxford was really like. Probably by me
