I only get to watch G4 when I visit my gf's folks, because it's not on our basic cable here. Soooo... that said...
My impressions of it are mostly positive... although the Whip Set and the car shows and that drama with Bill Bellamy need to go.
I enjoy Judgment Day. Lucas and Tallarico play off each other nicely, the show's production values are decent, and the reviews are mostly enjoyable. Except when they end up with a fighting game. Ooch. Hire a guest reviewer for those.
X-Play hurts me. The content is fine. It's the hosts that bother me. Actually, I can stomach Sessler (is his blood infused with caffeine?!). It's that girl to his left...whatever her name is... the one you guys wanted to see nude in Playboy... Everything she says seems scripted and fake (assuming, of course, everything isn't scripted and fake). Maybe it's just her mannerisms. I dunno. I just can't watch her for more than a minute before my head hurts.
Attack of the Show... I don't know why you guys hate on Kevin... I don't know what he did before, but he seems just right as host. I enjoy the content. I enjoy the format. The chick that does the links is listenable. Can't remember who the old co-host was. Hope the new one is decent. Saw an episode with Seanbaby. It seemed like they wrote some decent dialogue for him... or maybe he just looked THAT comfortable. Saw an episode with Jeff Gerstmann in it too. He seemed less comfortable, but they also gave him like half the camera time. Course, he'd been down there already working on those Cinematech episodes...
I dunno... I don't get the chance to watch G4 day in and day out, but it sure seems decent when I do get the chance.
