It's easy to dismiss A Channel as another Cute-Girls-Doing-Cute-Things moe fest, at least upon initial viewing, but the show runs much deeper than that. Focusing primarily on the relationship between Run, a lovable idiot, and Tooru, a girl one year her junior who chaperones her through life, A channel builds to a crescendo as Tooru begins to fear losing Run forever as they move on in life, only to realize their relationship is stronger than the school grade that separate them. Cleverly mirroring the Run / Tooru dichotomy is relationship between two teachers, and two other first year students, demonstrating that their relationship is truely timeless.
