I think it's a lot closer to The Day of the Jackal (1973) in spirit. Far far superior to The Jackal (1997 film).
I'm halfway through but still not feeling the romance story of the Jackal and his wife though. Think the show could have done better without it.
It's pretty much what happens with any show with a little gravity these days. Production value is through the roof, dialog is okay. But the show lacks depth.
So I'd say if you're looking for a show to watch and this caught your eye, just watch it. But don't expect it to be the best thing you've ever seen. Eddie Redmayne is good in it though.
