I agree that the processes seem highly complex. Though I've learned many of these molecules' individual functions before in biology courses, I still don't know many of the intricacies of their interactions with other molecules within a cell. Also, I'm interested in understanding the processes involved in "harnessing" these complex interactions (that were demonstrated in the videos) for product design inspiration in the business world. The videos are also helpful because I'm very much a visual learner. Earlier this year in BIO112, our class watched a video clip of kinesin "walking" along a microtubule. Before then, the only mental image of this process I possessed was a cartoon-like model from a textbook. It's wonderful to come that one step closer to fathoming (at least visually) how molecules move inside an organism. I enjoy reading and listening to lectures about the functions of "molecular machines," but I believe these videos make the subject--mitosis, meiosis, transport, and general molecular movement--so much easier not only to learn, but also to visualize and retain.
