I'm familiar with Sheen's work. I like the way he acts and the scripts he selects. 2 things astonished and delighted me about Good Omens 1:

1. The writing is a 10. Neil Gaiman and Terry Pratchett selected the most interesting subject to create a show and made a comedy jewel. I have only recently learned Good Omens' originated as a book. It is now in my shopping cart.

2. David Tennant is one of those actors who had passed me by. I remember thinking he was good. I suppose I took him for granted. I've never watched Dr. Who, or seen him in a Shakespeare play. 2 errors I plan to correct.

Tennant is BRILLIANT as Crowley. Recently, I coincidentally watched a couple of other movies he's in. He changes his voice and affects his accent perfectly each time. Tennant has created a specific walk for Crawley. The way he moves around Aziraphale at the Globe Theatre as a snake encircling his pray. The teen-like manner he moves when he's annoyed. Tennant is an 11 out of 10!

The only reason I gave this show 9 stars is I don't like the custom choice for Anathema Device. She's a contemporary "witch." I fail to see the point of dressing her like a dark Mary Poppins.

I haven't watched season 2 yet. I've decided to watch Season 1 again before getting to Season 2. I'm enjoying every bit of it! I think you will too.

EDIT: Just watched season 2. Terry Pratchett's input is really missing here. I can't help to think if he were alive, this story wouldn't have taken this direction. This has nothing to do with moral judgement. I just think part of what makes the show so compelling is it's interpretations of the portions where the characters intersect with passages of the Bible. The storyline has been completely divorced from the original concept on season 2. My score for this series is now a 7. Tennant is still brilliant.
