One of my favourite YT channels is Corridor Crew. It's basically a bunch of guys who run a visual FX house and they make cool vids utilizing their talents as well as reacting to good and bad effects in film & television. Here below is one of their most recent projects, an R-rated re-envisioning of the 1971 flick Willy Wonka & the Chocolate Factory.
