Kristen Stewart does fierce work as the radicalized '60s actress, but the biopic too often wanders elsewhere.

Seberg's life was quite interesting, but alas, this film is not, and that's a shame, because she was so much more than the girl in that iconic shirt wandering Paris with Jean-Paul Belmondo.

"Seberg" provides a chance from Stewart to move from hubris and naïvete, to fear and paranoia, and finally to a kind of fragmentation.

...the big news here is Kristen Stewart, an excellent actress and full-blown movie star, who puts everything into making Seberg, the character, into a three-dimensional, complex being...a great performance in a film that reins in potential histrionics...
