Okay, Mr. Pseudo-intellectual elitist. I know you got upset because someone insulted this little comic you love so dearly, but instead you should back up, and view it objectively.
This comic in question is a poor example of how to exposit a story.
You like this comic, for whatever reason. That's fine, but no one cares, and that doesn't make it good. I'm sure you agree with that statement on it's base level, but I'm sure you're thinking "I don't think it's good just because I like it." But really, you do, otherwise you would have a real way to defend why it is good exposition other than accusing those that don't like it of being illiterate.
It's mathematically unappealing to the majority of audience viewers, the balance of text to art is completely off.
If your text bubbles are 80-90% of most your panels, you're probably doing it wrong. This comic should instead of added more pages, since it had no good reason for this decision.
A lot of the things it does you could get away with in small doses, except this isn't a small dose. This is full speed the entire way through. Your comic should move forward in real time, especially if it's trying to portray something realistically. It hardly breaks away from his giant speech to show the girl's reaction for a moment, or him do anything other than shift a few inches and move the camera. If this were a movie you'd see him talk for a few minutes, see her face as he talked for a few minutes, then see him talk for ten minutes. And that would be terrible without a good reason.
