( CNN ) -- Of the eight `` Harry Potter '' movies Daniel Radcliffe made , there 's one in particular that sets his teeth on edge . The 25-year-old actor , who portrayed J.K. Rowling 's adolescent wizard hero for 10 years starting at age 11 , admits to the Daily Mail that it pains him to watch 2009 's `` Harry Potter and the Half-Blood Prince . '' `` I 'm just not very good in it , '' Radcliffe bluntly told the UK publication . `` I hate it . My acting is very one-note and I can see I got complacent , and what I was trying to do just did n't come across . '' It 's not that Radcliffe is ungrateful for the experience . On the contrary , he calls the opportunity to play the globally adored character `` an incredible blessing , because it gave me this opportunity to start a fantastic career . '' But Radcliffe was still getting started as an actor when he was cast in 2001 's first `` Potter '' film , meaning the franchise also holds `` the moments I 'm not as proud of , '' Radcliffe said . `` Mistakes other actors get to make in rehearsal rooms or at drama school are all on film for everyone to see . '' Though admittedly self-critical , there is one `` Potter '' flick that Radcliffe is happy with : `` My best film is the fifth one , '' he tells the Daily Mail of 2007 's `` Order of the Phoenix , '' `` because I can see a progression . '' As he 's taken on more complex and varied roles in an effort to leave Potter behind , Radcliffe has become more confident in his talent . In August , he stars in the romantic dramedy `` What If , '' playing a character that 's `` someone most like myself , '' he told the Daily Mail . `` I 'm definitely the geeky guy who wants to be in a relationship , '' he said . `` And it was a big thing for me to do a modern-day romance . There was no point in this film where I had to get covered in blood or cry over the body of someone or pull someone out of a muddy bog . '' No more 'Harry Potter ' films , Daniel Radcliffe says .
Daniel Radcliffe is n't keen on the sixth film in the `` Harry Potter '' franchise . He feels he 's `` just not very good in it '' His favorite installment is the fifth film in the franchise .
