Exceptional additional content would compensate for that, though. I'm not going to throw money at a commercial enterprise that already supports themselves with advertising money out of a fucking obligated sense of charity. Next time my subscription lapses, I'll have to re-evaluate things. Other than quick-looks, most of the content here really is just the same stream you get on any other RSS feed about trailers and general bland industry news, peppered with the occasional attempt at "journalism".
The weekly "live" thing originally kind of sold me on it, but then they started padding it with content that just wasn't interesting and it died.
I still dig GB, but I can't help but get this sense that they are a bit lost, wandering, and uninspired about their jobs and the product they output.
Hallelujah my brother preach that gospel!
