I will say that I'm a HUGE fan of Attack on Titan. I greatly enjoyed the anime and make a point to purchase the books when they come out. But when I saw this video, I was actually excited to see what these guys have to say. Because there are some SERIOUS problems with the manga (one thing that always distracts me is just how ugly some of the art can be. Peoples' faces look like they're always caught in mid-scream even when they shouldn't be. And the sooner the most recent arc in the manga gets finished, the better).
But this video....how much time do they actually spend discussing "Attack on Titan" and not "this is a microcosm for what is wrong with anime/manga as a whole"? I want to see what they think about characterization, the art style, the plot, things that are specific to the series itself. When they were talking about how the anime has to cram a lot of characters that they want us to care about in the second half, that was something I found interesting and wanted to hear expanded on. But that point gets dropped before they go anywhere with it.
I get that neither of the two guys are anime fans, that's perfectly fine. I'm all for hearing them discuss But if you're video is going to be discussing the flaws and shortcomings of a series, I would hope that you actually stick with that premise for the entire video.
EDIT: Also, if you want a great anime series: Steins;Gate, Fate/Zero, and Romeo X Juliet. I happily recommend all three.
