Very disappointing. Why they decided to completely change the story is beyond me. They obviously couldn't fit the entire novel into a two-hour film, but c'mon. Story changes aside, it's a very entertaining movie. Impressive action sequences, nice needle drops, fantastic cast, (Ben Mendelsohn, Simon Pegg, and Mark Rylance are standouts), and great visual effects. The film does a good job of visualizing the OASIS, it's pretty much how I envisioned it while reading the book, they add some great stuff that just wasn't around when the book came out that I really appreciated. It's just, the story is not good. They basically take the basic idea of the plot and do whatever they want with it, and that's very frustrating. Ready Player One is my favorite book of all time, and the film adaptation is very disappointing.
