soooo many things to choose from but the thing i probably like most is that he acts like a normal teenage boy, he's not a fake, hollywood, american dream perfect, flawless boy with the teeth that could blind blind a person and the million dollar smile, he makes his mistakes, in fact he makes alot of them, but that's what makes his character believable, for me lovable, relable and allows a viewer to develop real feelings towards him as a character be it love it or hate..and that's the biggest reason why i love my Finny bear. :)
I think he is the most innocent character in Glee.And also the one with the beautiful smile always.Because of that feature of him he looks like an ANGEL to me..........
