I did mean Interstellar. Only a few trillion miles difference.
Primer is fun.
I don't deny that Tenet has a slick production and can be nice to look at, but... Yeah, there are dozens of time-travel films around, and pretty much all of the ideas in Tenet are covered, and the ones that aren't turn out to be sort of daft after a moment's thought. Like inverted bullets. Compare that with the astonishing but awful 'death of Seth' in Looper. That's a twisty (and twisted) time travel idea.
Yeah, I can't remember Looper properly, will get around to a rewatch of that sometime I'm sure. Absolutely wouldn't bother myself trying to defend Tenet, no worries.
