Saw the first two episodes. Nicely done. Actually, is more entertaining (and realistic) than, for instance, The Americans (a tv show that did not age well, imho). The story seems to be based, partially, on the case of Ion Mihai Pacepa -- former head of Romanian Intelligence services, who defected to the US. The show also combines other elements from the bios of local communist party bosses. In any case, it is a much better show than other tv shows produced by HBO in Romania. The acting is better except for the lead actor, who has a flat, boring way of delivering his lines, with no emotion or nuances.
