Yeah, when I first saw it on TGWTG, I thought it said eSluts as well. Sadly, it's not.
Walker got in real deep with Demo Reel (from what I've heard, he spent upwards of $250,000 USD on it) and it tanked bad. He's gotta recoup, so he brings back Nostalgia Critic. Except that's not doing so good now either, since viewers either stopped watching because they were tired/sick/etc. of his shtick and/or they hate the new long, dragged out skits in the reviews that feature the talentless smucks that were in Demo Reel. So he's gotta do something to make his scratch back. Hey, people make money off YouTube, and people use clips from him as forum weapons, why not do it himself? Brilliant, except he makes new unfunny ones that are too long to use as forum weapons that feature the talentless smucks from Demo Reel that try really really hard to be funny, and LIKE ME PLEASE!! So, not brilliant.
Which is sad. I used to really enjoy his videos, but then he got really full of himself.
