Surprise, surprise, "The Last Ship" offers a surprisingly strong finale, which ticks all the boxes and will keep the viewer waiting for more.
Chandler's family is sick, Alisha Granderson's mother is in Baltimore and they seem to have some kind of government, Titus Welliver's Thorwald looks mean and menacing... But we have got the cure, right? All is going to end well, it has to. No? No?
The plot teases us with a new bad guy, Thorwald, and the new danger; the warlords that have been popping around like mushrooms and want to be in control of things. And then hits the viewer with a lot of interesting and inspired plot developments. The fast pace won't let the viewer breathe, and, curiously, all the characters get interesting arcs and stories (all the relevant ones, at least). The direction is good, and the action more than just people shooting in the dark (all those bad shooters in previous episodes...).
"No Place Like Home" is lots of fun, and delivers on the promise of the show. And it ends with a lot of interesting questions that will need to be answered in future seasons. A great finale.
