I love this video and I agree that we tend to make entirely arbitrary decisions about what is and is not intelligent, which is far more a reflection on our own preconceptions than the nature of intelligence, but I would note that bacteria have a completely different experience of their environment than we do of ours, and always have a bit of a frantic vibe to them. On their scale, they are moving through molasses while being buffeted by particles causing them to turn and spin; they are entirely incapable of moving in a straight line, and their motility is fundamentally random. So they always have a sort of vibrating, frenetic quality to them.
