Liked the concept, hated parts of the story. There is no way in hell Tinker from the nuked Earth would be able to create a device like that in hours, even if he was an electronics genius.
Other than that pretty decent movie that would make an excellent mini-series.
Not sure if he was really from that earth. He seemed to know an awful lot about the building, what it did and how. I'm guessing he had the plans all ready to go.
It's not a plot hole. That's not what ''plot hole'' means. He's some sort of engineering genius. It may be unbelievable, ridiculously so, but that doesn't make it a plot hole. The plot is sound.
I find the idea of a building traveling through the multiverse to be quite unbelievable as well. Doesn't make it bad writing.
Actually it is a plothole. He knew nothing about the building or the parallel worlds and had never left his own world, that's pretty well established. The world he came from was on par with "real earth" tech. The second world was hyper advanced, decades ahead of the other worlds. Even for a person with high aptitude, learning a contemporary system well enough to engineer advanced software takes a significant amount of time.
What this scenario did is essentially like taking an engineer from the mid 90s, handing him an iPhone 6, a 3D printer, some spare electronics which aren't designed to operate together, and then asking him to use those parts to solve one of the advanced technological challenges that modern scientists who are deeply familiar with modern tech have been unable to solve after years of collaborative research and billions of dollars of R&D funding, and to do it alone in an afternoon.
This was not a case of asking Station, the greatest scientist that ever existed anywhere in the universe, to build Good Robot Bill & Teds in the back of a van with basic parts from a hardware store. Sufficiently advanced technology is indistinguishable from magic. He wouldn't even know how the future tech works in its intended form, much less how to adapt it.

That's still not a plot hole. It's a handwave. It also seemed to me that it was implying that the old man was connected to the building in all his alternate incarnations...or maybe that was just me. If this got picked up as a show I fully expected them to run into another version of him and find out that he could screw with the building too.
He had nearly 36 hours to do that magic box. Also you assume that his world was not very advanced. But it was stated that world was nuked with Pakistani nukes and that nuke which killed Tinker's family was suitcase bomb. Pakistan got nukes in late 90's and they still don't have suitcase nukes. So we can assume that Tinker's world is/was more developed than ours. Maybe it was even more developed than that world they jumped. So it was old tech for Tinker.
Also Tinker had video about delivering that bomb, so he knew that building and was watching it.
I assume Tinker was one of those jumpers and somehow settled to that nuked world. Maybe he found it to technically advanced, his secret love liked him in this world and he settled there until it was nuked. And because he knew it jumped randomly he wanted to find a way to travel world he liked, not another failed one. So he had visited that building million times and had planned ahead how to make that magic box or it was almost ready and he just got final parts from that tech world.
I am sure that Tinker didn't die when he was shot, so he would have returned if series would have continued.
