I wouldn't say Dan is overrated. I mean, it's not like he's been nominated for an Oscar or anything, but I feel he's rather untalented. He seems to be an interesting bloke in real life - comes across as grounded, well-read and well-adjusted, but he was miscast as Harry Potter. Actually, I felt he was perfect as Harry in the first three movies, but then he just didn't grow up to look anything like how Harry Potter is described in the books. As often as not, Harry comes across as wooden in the films, or unemotive.
TBH, barring Rupert Grint, neither Emma Watson nor Dan Radcliffe do justice to the characters of Hermione and Harry. The Potter movies are peppered with an embarrassment of riches when it comes to supporting actors (Maggie Smith, Alan Rickman, Helena Bonham Carter, Richard Harris, John Hurt et al), but they got 2 out of 3 right when it comes to the main cast.
