Definitely needs an epilogue, and I hope we see Jod again.
I wonder whether the physical setup was somewhat inspired by General Atomics Galleria in Fallout 4. In that scenario the General Atomics Galleria is a commercial space run and staffed entirely by Mr. Handy robots with "The Director" being a Mr Handy who supervises from the top of a tower in the Galleria. You, the player, can claim to be the long overdue Supervisor sent by General Atomics for the Grand Opening. And, you know, the whole fact that the outside representative finally shows up after 200 years is pretty much bang on. And if the Barrier is basically an analogy for a Vault and the Great Work is like the "missions" of the Vaults... Is this seriously a Fallout movie in Star Wars, D: ?
