While I am happy the Nostalgia Critic has returned, even making a review lauding "The Review Must Go On" I think he prematurely pulled the plug on Demo Reel. This is coming a guy who wasn't particularly impressed with it. Demo Reel was a show within a show/mockumentary about an ambitious aspiring director named Donny Dupre, and his "quirky" and longsuffering crew members who were tasked with remaking films a la Be Kind Rewind
or Amanda Show's Block Blister. The real weakness of Demo Reel, in my opinion, was the comedy. The entire premise is fairly unoriginal and the delivery wasn't particularly better than what can be seen by college humor or smosh. What made the series appealing was the drama (ironically), looking at the characters and their various issues was the reason I kept looking back. If you look at some of the early Nostalgia Critics the episodes weren't always golden, yet he persevered and became the big name Internet Celebrity he is today. I think Demo Reel should have been treated the same way. It could have been a monthly special set in between the Bi-weekly Nostalgia Critic videos. Heck, maybe even quarterly so he's not overwhelmed.
A similar Replacement Scrappy
effect happened to Bowser Jr. and the Koopalings in the Super Mario Bros franchise. Junior wasn't well received because the fandom thought he replaced the siblings. When introduced in a game together people warmed up to Bowser Jr. I would argue the same would have happened for Demo Reel, instead of replacing one for the other, make time for both.
