Just watched the finale - so spoiler alert if you haven’t seen it:
A lot of fans are howling their dissaproval as too much was left up in the air and the show has been cancelled - all the sets and props have been dismantled.
[spoiler]I actually thought it was an awesome ending, and explained it quite well. John was protected by the T1000 as Weaver by jumping him over the dangers of Judgement day and right into the safety and protection of the crew of Allison, Kyle, and Derek and some dogs, with the cyborg there to continue to aid and protect. He now can offer his expertise and leadership to the fledgling resistance.
His mother stayed behind with Ellison to continue to take down threats that they could do something about, and eventually dies of cancer. Cameron gave her chip to John Henry who downloaded his AI and jumped into the future before they arrived in the room. He is now there to offer some hope of defeating Skynet. Her body was too badly damaged with metal exposed to come through.[/spoiler]
Thoughts? For my money that offers enough of a conclusion to a great series.
