why do you like to watch re-enactment videos? I dont understand what it is about them that some people like to see. And post on forum later

In fact I dont understand why people like to re-enact anyway? If it was for a movie or something, it would be very cool. But to practice and dress up in coustumes, just to do some simple moves synchronized I just dont understand that. No matter how intrested in military history, I cant imagine what makes people do suff like that.
