I agree. Gravity, Interstellar, The Martian all did well well financially.The existence of critically acclaimed sci-fi movies like Arrival in recent years makes it clear to me that there still is an audience for sci-fi films which are not dumb action blockbusters where the heroes defeat the bad guy. If only someone would tell Paramount that.
But those movies are fresh new entities and I think that sparks interest. Star Trek doesn't feel progressive or new. It's just re-hashes and nostalgia. Star Trek parodies do a better job of societal commentary than actual Star Trek does these days.
I don't know what needs to be done in order to refresh the franchise, but I feel confident in saying neither does Alex Kurtzman.
