I gave Ready Player One a second chance the other night after giving up early the first time I watched it, and I was obviously in the wrong mood the first time because I loved it. So much so that I have started reading the book of the same name by Ernest Cline. So far (about 10% in) it's bloody fantastic and I can't wait to finish work and carry on reading it
I read somewhere, and I can't remember where, watching a film first will not ruin a good book if you read it afterwards, but reading the book first will ruin plenty of films.
