I don't mean to nitpick, but "The New Adventures of Mighty Mouse" (Filmation, late 1970's) is a completely different series (albeit with the same character).
Anyway, I don't have much to say about him, especially since I only follow family-friendly stuff. I will say this. It is unfortunate that both he, and "Mighty Mouse: The New Adventures" were both eventually found "guilty by association" because of the whole "Littlest Tramp" thing....
