This is sort of what the report of the week ('reviewbrah' [0]) is doing, no? Reviewing fast food in a quirky manner. Million+ subscribers on youtube, really interesting to have followed this for 5+ years when he had a few hundred subscribers.
Doing the exact same thing with very small refinements, over and over. It's not that glamorous, but I reckon at 1M+ subscribers he is doing quite a lot better than many obscure luxurious lifestyle personalities.
