Such a rip off...
I just saw this movie and i'm pretty angry that i actually paid to see that.
The actor playing Serge is really convincing, but the movie is just a pain in the ass, with a clumsy mise en scène, ridiculous ideas and poor renditions. I checked my watch three times, wondering it there would be any "take off". Nope.
The biggest mistake made in my opinion was the very unaesthetical animated caricature of Gainsbourg, his "double", following him (way too much) during the whole movie. So ugly and out of place. This is not an animated movie, for god's sake!
I don't know, it's hard to list all the annoyances i've felt during the whole movie, but there were too many of them...The caulliflower impression, the awkward situations where you feel like you're caught up in a soap-opera..Lots of bad ideas and in the end a lame, very lame "tribute" to a major figure in French musical landscape..
It doesn't take just one (good) actor that looks like Gainsbourg to make a good movie about him...It also takes a director with interesting ideas and a bit of seriousness, which is really lacking here.
And once again i gave money for a piece of sh**. Nice!
