Eternal Sunshine of the Spotless Mind - both beautiful and sad. A rare comment from me: I tend not to associate beauty to sadness, or vice versa. I find sadness rather ugly most of the time.
But this film was both these things, with portrayals bordering on perfection, in particular Jim Carrey. I can't find enough praise for his character portrayal, thoroughly believable.
There were moments of beauty in the script, the visuals and the character expressions.
There was sadness in the story and the aftermath. I came away with this feeling that they will simply relive the same love story over and over, doomed to repetition of failure, over and over, for life.
