Emily Mortimer, I think she was in The Newsroom and was quite good there.

As far as the show, the first season was entertaining. The second season a little less so, though nice to see New Vegas again. Lots of fan service across both. However, I did not find either very memorable. It’s fun to watch but very forgettable. I suppose it’s like how Bethesda games have the breadth of an ocean (or at least a large lake) but the depth of a puddle… or to put it more accurately to how much love they put in their games, a puddle of dog piss on the asphalt on a hot summer day.
