Before the spring season, Tanaka-kun was a maybe on my list, then it went off my list, and then it went back on my list after I saw people still talking about it a few episodes in. The three episode rule is a great guideline guys, if you still see other people talking about a show after three episodes then by golly, then you gotta check it out at that point!
