Sludgey didn't ruined anything, in fact, it was made better!
Reviews for "A Chad and Sludgey Christmas"
The animation looks really good and the voice acting is great as well.
Really enjoyed this one. Merry Christmas! :)
The animation, characters, voice acting, and story were great.
My only gripe was that the animation could have looked smoother and the grain should be removed.
But overall,
Excellent work.
Pretty good. The stop motion feel was done well and the meta jokes were pretty funny.
