Did You Know?


The episode's title, "YHWH", refers to the Hebrew characters known as the Tetragrammaton, and appears almost 7,000 times in the Old Testament. The ancient Hebrews took the Commandment against using God's name in vain very seriously and therefore refused to write His name in the Old Testament, choosing instead to abbreviate it. English Bibles usually translate it as "Lord of Hosts," or simply as "Lord." The actual name for God the Hebrews used has been lost to history but most believe it was "Yahweh," although some use "Jehovah" instead. See more »

Best of the rest
12 May 2015 | by (Chicago, IL) – See all my reviews

I've enjoyed POI from the beginning and while at points I questioned the direction it was taking I think that the 2015 finale YHWH was by far the best and while wrapping up a lot of story opens the door to even more. It brought us to a "face to face" showdown which left "the good guys" playing catch-up but a chance to see an edge of your seat battle to the death that wiped out some story portions I'm glad to be rid of, but written into the overall battle between the AI superpowers and their backers where one is taking over while the other simply trying to survive to fight another day. Great end and launching pad into next season. Nice to see John with all his unbelievable moves go into superhero mode and take out a small army in the last stand as we get to see a surprisingly emotional ending with our team walking off into obscurity certain that next season will start with the attempt to re-launch the machine and obtain supremacy once again. While that seems obvious the backbone of some stories are now gone while the foundations for many others have been laid. I think next season can only be the launch of a second wind to the series or its demise, but I'll be watching to see! I'll be pulling for a bigger and better continuance!
