Frantz
First of all, I love the play between black&white and colour.
I guessed the twist when he first met the parents and i think it was pretty predictable but i didnt mind, i dont think this is the kind of movie that relies on big twists.
I liked the ending, it fit the movie well, and while a part of me wishes they ended up together, in the end, it would have essentially been her replacing Frantz with the closest thing she had to him, which ultimately wouldnt lead to eighter of them ever truly moving on.
The acting performances in this movies are all brilliant as well.
