Making it interesting?

So one of the comments I received back on my draft is how will I make one particular shot interesting. This shot is a very long one as it is Abby demonstrating how to hack a macbook account and it will be done internally through a computer screen. This could get very very boring very quickly so I thought some ways to make it entertaining would be to incorporate what is called "B roll" stuff. This is essentially clips that relate to what is being spoken about in the documentary and I guess everything that is not abby speaking directly to the camera could be classified as b oll as it is clips that relate to what she is saying. But anyway I was thinking of overlaying different clips of things like: teens slamming their laptops shut to represent their frustrations with social media or careless nature just leaving their laptop unaware of the danger their social media accounts pose to themselves. Teens whispering to demonstrate sharing passwords, a phone receiving multiple text messages regarding what is being posted on Facebook to represent the consequences of being hacked etc. These overlaid with the instructions for hacking, I feel, will make it much more interesting to watch.
