Liked it more than I expected.
As someone old enough to hate internet culture and the so-called breakout stars of YouTube, I found this a very funny (and deservedly so) on-point parody of internet fads and the transient nature of celebrity. Although I'm very conflicted that Shane Dawson is in this basically lampooning himself. And apparently the director also started out making online videos, so I guess it all comes full circle.
I thought all the actors (and their respective characters) were great at skewering their targets, and I even managed to feel genuinely bad for the "Wobbly Walk" girl. I had to look up Wendy McColm after this because she was so good in it.
