I think when people speak of Frank being one-note, they're talking about how he was arguably flanderized up till his final season on the show, such as how his lack of surgical skills were played up more and more, how much whinier and crybabyish he could get at times, and how all of his thoughts were practically consumed by Margaret when she got engaged to Penobscott.
When you look at Frank in the beginning, he's not nearly as surgically incompetent, he's more cooperative in OR, and he's even portrayed as something of a religious fanatic (albeit a hypocritical one).
But one thing I love about Flanderized Frank is that cackling laugh of his (that Larry Linville apparently ad-libbed once, and it stuck). That, and the childish temper-tantrum he threw in Margaret's tent upon learning Potter was replacing him was hilarious.
