after the post above I started reading the whole thread and I noticed the discussion about mixing comedy and drama in films, and well, all I can say is that this "mix" is the reason why I love movies.
most of my favorite movies come from this "genre", like The King of Comedy, Forrest Gump, Fargo, and the Tarantino's films.
in my opinion, when you say something serious in a funny way, and it still affects you seriously, it's gotta be great stuff.
