In my opinion...
This movie should've been made in color. I understand that they wanted to bring the artistic side of the story and the performances, but I think that in this case, colors were needed to perceive the essence. I love b&w movies, I just felt this way about this one.
Other than that, I wouldn't ramble on... I had a love-hate relationship with this movie the first 30 minutes, but I ended up loving it. Greta is amazing, no matter which character she portrays.
