I think the problem is that unless you have a very autistic interest in cooking then it’s not very interesting when done properly.
That’s when you see people over compensate.
It teaches people a lot of bad habits too. It looks cool and gives things a bit of movement and urgency watching people chop as they’re cooking but for Christ’s sake they should be teaching people mise en place which makes cooking a million times easier.
I don't think that's it; most of these people want to be "celebrity chefs" but without the personality or talent to back it up. (This is endemic to e-celebs in general).
If you look at something at
Emeril Live, a show popular in the late 1990s and early 2000s and perhaps Food Network's biggest star, Emeril Lagasse was more spectacle than chef. If you look up any old clips if you're not familiar you can easily see why some people thought of him as obnoxious and there are probably a bunch of fossilized Internet threads hating on him. On the other hand, spectacle as it was, Lagasse had a career. He was an executive chef of long-time New Orleans restaurant Commander's Palace and later opened his own restaurant, by the time
Emeril Live began production he had already made six cookbooks.
On the other hand, something more down to earth, like
The French Chef or
Good Eats, Julia Child and Alton Brown respectively, could show someone how to make something while still having an interesting and likable personality, with the formats of their programs being innovative enough to run for multiple seasons.
This is where these YouTube food shows fall short. Rarely is there talent involved—extensive editing covers up mistakes (I should mention that
Good Eats had a full staff with multiple stages going on, with what went in the oven in one scene not the same thing coming out, but at the same time this was explained in a behind-the-scenes episode) and these people ALL suck. They don't have inherent talent and in some cases are remarkably average, they're not that informative, and they're not that likable.
