If the movie is like the bombastic novel, then no wonder!
It would take a purist like Phillip Glass (who IIRC once rendered the entire bloomin’ Bhagavad Gita into an off-Broadway production — every single word of that turgid Hindu tome, in the original Sanskrit no less) to literally transcribe Ayn Rand’s book to the screen. And the result would play for maybe 6-8 hours. Who’d want to see that at all, unless it was as episodes in a series? Mercifully, this movie skips the monologues.
Read it again, you must have missed something.
