Luke Mochrie served as a fanboy of the Cinema Snob in TBF, but was also a fanboy of the Nostalgia Critic in Suburban Knights. While it's not in the movie how or why he makes this transition, it does bring up an interesting theory. The premise of Luke's show, Film Conscience, is about the two voices in his head (the cynical Phillip and the optimistic Ringo) that tells him how to talk about a film. In that regard, Luke (the character) could be interpreted as being very fickle and not knowing who to follow, especially considering how different the Snob and the Critic are.
