Ad Astra is more art film than thriller, more father-son reclamation than sci-fi, and more a drifting homage to Apocalypse Now in Space than something that can stand on its own merits.
The march of history may change the details from 11 to Eleven, but the core element remains; the heist by a team dedicated to pulling off the impossible.
I've been known to complain about the lack of good science fiction cinema these days, but I suppose there's rarely been a time when there were consistently good sci-fi films filling the theaters.
