Saw a screening last night, I thought it was good. It has a few laugh out loud moments. There's also a few boring moments where nothing seems to be happening just to build tension I guess.

I think the filmmakers intended that the viewers had all read the book recently. I had only read it once, when it first came out, and apparently had forgotten a lot, so there were many parts where I wasn't quite sure what happened or was happening...

Also a few bits seem unrealistic. And obviously that's kinda a dumb thing to say about a movie about magic... but I won't list them as this is a non-spoiler review.
