OK. I'm going to praise parts of the final episode, but I don't want anyone to get the wrong impression: that was pretty damned sucky and chock full of big steaming piles of stupid. I agree with pretty much everything that anyone has posted in the last day or so.
However, I am a big fan of giving credit where credit is due, and there WERE some crunchy nuggets of goodness scatter hither and thither.
First, I loved the two bookend shots of overhead Los Angeles. I posted a few pages back that I would love to see that same shot repeated each week, showing the gradual decline of the city. We didn't get that, but I was impressed by what we did get this week. The first shot appeared to show a dark but mostly quiet city, but as the camera shifted to show more and more, you start to see all the fires and quickly realize that things are not as quiet as you first assumed. The second shot showed how those same fires had continued unabated and in fact spread through the neighborhoods, burning uncontrolled in an expanding ring and leaving nothing but charred remnants behind. Again, I would have liked to have seen this over the course of every episode, but still: decent effort.
Second, the scene where Depp Jr. and Strand are trapped in the hallway with a small horde of approaching zombies. I thought the flickering lights that kept hiding the approaching ghouls was really well done. As people upthread said, the one thing this show has done nicely is to make zombies scary again, and this scene was a great example of that.
Third, and I think I might be alone in this, I liked the panicked soldiers forgetting any advice/experience they had learned in zombie killing and just reverting to their original training... and how ineffective that was. I'm not as big a fan of Brooks' "World War Z" as some here are, but one of his theses for why the military would not be able to stop the ZA, was that they were endlessly trained to fire at a target's center of mass with three-round bursts, and that would be worse than useless against the undead.
The scene with the soldiers at the fence was a great illustration of that idea. The remaining soldiers (presumably all the smart ones have bugged out already) are freaking out at the sight of hundreds of walking corpses, and they act like the panicked teenagers that they are: blazing away rather than carefully picking targets and getting headshots. Strand even comments on this as he and Depp Jr. make their escape: "Full automatic. Hmmm. We don't have much time."
Finally, many folks (myself included) complained last week that Strand giving the soldier little trinkets (the watch, the cufflinks) was seven levels of dumb given that anyone could have gone to any random Tiffany's and gotten better stuff with a crowbar and ten minutes of free time. This episode showed us that their deal went far deeper than that and that the soldier was trading keys and favors for something much more valuable than a Rolex. In fact, the watch and cufflinks may in fact have been a ruse to disguise that Strand and the soldier had a concrete plan to blow out of the site together and take off on Abigail. Nice.
