Boring at best.
Ok you have hired A-list actor doesn't mean the show will be a success. While every actor does brilliant acting. The story is extremely predictable using the same character going back and forth. There is no character development even for the villain. Characters come and go without a storyline.
The screentime is maximised for A-list actor even though there is nothing significant going on. I have watched slow burning show like better call saul etc. but this shouldn't have existed for 8 episodes. This should have wound up in at max 3 episodes.
