Casting for Crowley and Aziraphale is fun. As well as the interaction and world-building that surrounds the story as well. However, I didn't quite enjoy this as much as everyone else seemed to. The special effects and Bentley are spectacular but the story often feels a bit disjointed and sloppily put together. Costuming is great though and there are many Doctor Who easter eggs were thrown in that are also a pretty fun time. If you've read the book maybe your experience is different but personally I didn't feel like each episode meshed together all that well. Still, a lot of comedy and a lot of fun.
