You can hear from the man himself

To be clear, NC won't be a regular thing, the character might come up once in a while, but the people involved in the project decided to take the next step.
So how do you feel about this, in general?
Me, I'm kinda sad, but for the most part glad it's over, the show was starting to get a little stale, I'm sure it hasn't escaped their attention that the videos reviews must've been declining in views.
The limit scope of the Nostalgia Critic which were shows that me and a few of us here were kids and seeing through adult eyes. There is only so much material that you can mine. They had already done most of the major "famous" bad films early on and as such the more obscure ones become a gamble.
Regardless, it was fun while it lasted.
