This is a huge waste of time unless you're a super fan. People keep saying there's some deep stuff about mental health in the last chapters but it's really not deep at all. He drank too much for a couple months, got sent to a pricy rehab, and realized he didn't love his girlfriend, and that's about as much as he let's us into whatever anxiety and depression he keeps referencing runs in his family. A good test for a celebrity memoir is whether it would still be interesting if the person weren't famous. If this were written by an extra on the movies, it would come across as very basic day to day behind the scenes of Harry Potter for most of its duration. On top of that, I'm sure this was his editor and publisher and whatnot, but the insistence on relating everything to Potter was honestly weird and off putting. You don't have to point out that a bank in real life doesn't look like Gringotts. We have been to banks and also that is from a fictional story. Ultimately this is the very average life of a very average white English dude who happens to be in some iconic movies, and it feels like he's aware of his complete lack of anything interesting to say.
