1) It was written a fair old while ago, so all his newer works (I think Four Rooms is the last film the book discusses) are not here.
2) He's not that an interesting a guy (at least when this was written).
That said, it does provide a lot of detail about his early and adolescent life, how he came to love movies, and a lot of background info on Reservoir Dogs and Pulp Fiction. And, like me, if you are interested in Tarantino full stop, then that's good enough.
Be prepared though, to come out with a slightly different, more cynical, view of the man.
