Oh, I wasn't disagreeing or thinking you were saying otherwise, I just wanted to make clear that it was more than just the woo woo that was unrealistic. The "love is a force that transcends causality" thing was obvious but the actual physics stuff was just as silly for the most part.

For example, if the black hole's accretion disk was putting out enough light and heat to keep orbiting planets habitable, then trying to fly down to the event horizon would be basically the same as trying to land on the Sun. But the plot needed that to happen so down they went.
