From the episodes I watched while they were here, I liked the information they relayed about how the industry works, but that's about all I liked. They seem to know what they want to talk about, but I felt their presentation of that material was awful.
For one, that voice is horrendous. If that's his natural speaking voice, I apologize, but they need a new reader. If it's been manipulated to make it high-pitched, it should stop. It's annoying, and the cartoony sound of it destroys (what I assume is) their serious tone.
Second, the writing makes it sound too preachy. It doesn't help that the artist draws him at a podium when talking. I realize that the writer wants to convey an inspirational, "we can do better than this, guys" attitude, but there has to be a better way of writing it. Also, I don't like that they group everyone together, as if every gamer has the same opinion on things. And then saying that "we as gamers" need to do X or Y, or something else. I don't like people speaking for me.
And I'm not all that fond of their art direction. Half the time it's that guy at the podium, a lot of time it's some stupid internet meme, and then occasionally you find something new. Maybe it's just me, but I'm tired of slideshow-style discussion shows. If you're going to recycle the same four drawings and fill the rest with things you found off google image search, just do an audio show. Same goes for MovieBob and his eight or so expression faces. I wouldn't mind listening to audio only, or reading an article. I just feel that if you're going to make me watch a video, the visuals should add something, and not waste time reminding me I'm listening to someone making a speech.
Back to the real question, I don't feel they're entirely full of it, but I do feel that the way they present themselves leads people to believe they are. And that seems to be a huge problem, judging by some of the other responses. It's not that they don't have a clue what they're saying; their credentials seem to indicate they do. It's that they're poor showmen, and can't seem to express themselves without coming off as overly preachy.
