So it all comes down to this. It’s the mega-length season finale of “For All Mankind,” in which many plot threads and characters will be explosively resolved! (But what of the vending machine? Won’t anyone think of the vending machine?) We get information about our surprising new character, Dev and Margo offer final(?) pep talks, Jimmy struggles to do the right thing, Molly talks Ed through trying not to crash, and we count references to “Watchmen”, “Apollo 13”, and even “Goodfellas.” Finally, there’s the needle drop for the 21st century, but it’s showing us a rather unexpected location. See you next season!
