It's interesting to note, I think, that a friend of mine who knows typology and did not read the books, but watched the movie, immediately typed Harry as an NF of some sort, while most people who read the books will peg Harry as an ISFP.
That being said, what really was frustrating about Dan Radcliffe's early Harry performances is that he really lost all that rage, anger, and really the beserker aspect of Harry's personality. The rough edges were rounded off, so to speak. However, I think he more than made up for it in the recent one. When he walked to his "death", it was a perfect moment.
