The absurd "comedic" elements ruined the movie
Like for example, the scene at the fancy club where Cabiria does a ridiculous dance. Maybe that type of thing was amusing to Italian audiences in the late 1950s, but in the modern age and to a more "Western" viewer, it just looks cringe-worthy. It was not the least bit amusing. And there were other scenes that were intended to be amusing, but they only served to ruin what could otherwise have been a very captivating movie. In fact, the ending of the movie seemed out of place with the rest of the movie. The last 15 or so minutes of the movie were astonishing, and Masina's acting was on point. But, it's hard to take this movie seriously, when it contains a handful of absurd "comedic" scenes.
I originally thought that this would be a very serious drama about a prostitute who longs for love. I had no idea it would turn out to be "tragic comedy". I don't think it's a masterpiece. It's a good movie, could've been great, were it not for the attempts at being amusing. I don't think I could sit through this movie again.
I did however re-watch the ending sequence because the first time I saw it, it left me confused about Cabiria's smile at the end. At first, I thought that the smile meant that she had gone crazy (due to the traumatic nature of finding out that Oscar wanted to kill her and left her penniless). On the second viewing however, I don't know what to make of her smile. Could it be that she genuinely (and naively) thought that she could just pick herself back up after what she had been through? Who knows. I guess we'll never know the answer to the reason for her smile.
