Serial Lover

So, OK, the others users say everything about it. It's very funny, very black humor. This is also very original and creative. We also got a chance to see Michèle Laroque starring in a movie. In French Cinema, she's always fourth of fifth on the bill. But there's one thing I really hate about this film : this is a French movie, so why the title is in English? Did Americans gives French titles to their movies? No! So why did the French do that (there's also their movie Sitcom, with an English title). And why all the songs of this French movie are in English? Did France have problems with their own identity?
