Mine are the following:
The Great Gatsby - I read this a couple of years ago and was disappointed with it and thought I'd missed the point. Gave it another the other day and finished it in 2 days (short book). No, still not getting the hype. No likeable characters either.
Catcher in the Rye- Nothing really happens.
Middlemarch - My fourth attempt at this... I will finish it this time!
The Time traveller's wife - Page turner, yes but "must read", no, no, no!
Started Early, took my dog - I normally love Kate Atkinson and really enjoyed the first three Jackson Brodie books but I found this dry.
The Da Vinci Code - Couldn't get past the first chapter.
