Do the how I can make you a millionaire intro videos on affiliate marketer sites work?

I was doing some research and came across some IM marketing guru sites where the home page kicked off with a video of them outlining how lucrative their business is and showing their Ferraris, palatial homes, toys and all the dough they are rolling in.

I wondered how effective these videos are and whether people actually are attracted to videos like this? They seem a little in your face to me, but people must respond to them if they are up there.

I can see that they would appeal to the masses to a degree but is this the best way to engage and sign up new affiliates for a marketing program?

On the whole, do you think videos are more effective on a home page than content and imagery, or do you think the visitor can explore in their own way without the video pop up?

I am more of a facts person and I like to see the info in an infographic or written down, and the showiness of some of these gurus aren't really my cup of tea but I am interested if this is a technique that really is working for people.
