But it didn't go according to plan as we're clearly shown at the end of the episode. In terms of the directing, dialogue, acting, set-pieces even to cinematography it was well executed. As far as the infiltration goes, that was done really well, in multiple scenes we see the main characters at risk, the team was split up at which point each of them were vulnerable. Abraham was almost taken out, Sasha saved him, alarm was signalled, Negan gang start pouring out. Glen & Heath cornered into a room. Aaron also caught slipping helped by Rosita. There were a few other instances where unprecedented situations occurred.
It was one of the most enjoyable episodes by far that pretty much excluded zombies.
