Convincing
At the end when DD leaves the cafeteria, the music is very nicely composed... CGI, many goods things in this decent movie.
I guess it's not highly rated because there is no (romantic) happy-end, but remember this was so in the comic, Daredevil just had to stay alone (like 007, Mike Hammer.. many).
Edit : The idea of viewing by the mean of rain is also in Dino Risi's Scent of a Women (1974)!
