  • Peeking at the script, I think this was the scene that annoyed me.

    “It seems like if any of these numbers of prime, then the room is trapped. Ok, 645… 645, that’s not prime. 372… no. 649… Wait, 11 x 59, it’s not prime either. So that room is safe.”

    The pauses after 645 and 372 are pretty bad. The line should have been something like “645 and 372 are not prime. 649…”

    As at the moment she was operating under the theory that only primeness mattered, anything with an even number or a five should have been instantaneous. 3s take a second to check (add the digits and see if that’s a multiple of 3). The rest of the primes up to 31 are tougher. (Well, you only have to worry about 961 for 31, as otherwise a lower prime will interfere, but eh.)
