Very true... I think Antonioni usually does have a bit of light in his films, but some of them end on a very sour note. I always thought BLOW-UP ended on a very strange and somewhat bleak note -- very unsettling, especially for the time period, and was always interested in why that film was so damn popular (don't get me wrong, I love it, it's one of the best films ever, but it doesn't seem like the kind of movie most audiences would want to watch over and over again, despite being a mainstream success).
