(SPOILERS)
Amazing idea. A lot of issues covered in other reviews that I agree with however the logic and plot holes is something I haven’t seen spoken about yet. The main thing being plot holes in S3. S3 while the idea is good, the execution seems lazy and it’s such simple mistakes. They just seem to change the rules of the keys and how they work. Gideon talks keys off the lockes when they’re offered out when we know that that’s why his 2 henchmen are there. Could have easily been fixed by locked surrendering the keys by putting them in his flat hand, not holding them up for him to take.
Gideon uses the anywhere key and takes himself to the woods where there’s no doors, never mind ones he knows the appearance of when we know that the key has to be used to go through a door that you can imagine because you’ve seen it. Hence the discovery of the key when bode couldn’t take Kinsey to the Paris cuz there wasn’t a door to go thru, and also bode being sent a pic of rufus’ door in Nebraska so he could come visit. Could have been fixed by Gideon simply going to a different location that made sense.
Finally the time shift key. While the last moment of the series was sweet. We’ve made it clear by dodges reappearance that if you’re in contact with the traveller when they shift back, you’ll go too. Which is how dodge got back with bode. But we see the whole family hugging Randall as they shift back and Rendall isn’t brought back to their time. That’s not how the key works!! Frustrating to see such massive errors.
