i did enjoy the film, yet going by the name of the film,
what i would have changed is the theme being the 20th-century girl, trying to portray a movement in a girls life around the turn of the century. First half showcases the youth making us endear to the FL and ML and then the second half showcases the FL slowly forgetting the ML as she has no idea what happened to him and growing up. then this film comes to her and she watches it and re-remembers the time and memories of 20th entury.
but as i typed it down i feel it might also might not be something i would have been 100% happy with.
