I like the Nostalgia Critic, the Nostalgia Chick and Linkara, though I think Spoony is okay as well. I think especially because I've seen quite a lot of the movies he's reviewed as a child, I can relate a bit (Jingle all the Way is our family Christmas flick

).
One of my favourites who few have mentioned so far though is the Cinema Snob. I quite like the character and I suppose I'm slightly biased because I myself ashamedly quite like some of these horror and exploitation films, so I suppose I have a point of reference there (which I guess is why I quite like some of Brad's regular reviews too, because he reviews quite a lot of the kinds of movies I like seeing).
From one of the Godfrey Ho movies he reviewed:
