Honestly, I love romance movies, even the ones with sad endings because they poatry a beautiful journey but this movie was something I have mixed feelings for. HERE ARE THE POINTERS-
1. I understand that Katie did not want to tell Charlie about her XP but it wasn't something to take so lightly for and go out the whole night and then basically plot your own death!
2. THEY COULD HAVE JUST SHOWED THE LIGHT EXPOSURE AS AN ACCIDENT WHICH WOULD'NT BE REPEATED AND SHE WOULD LIVE UPTO HER DISEASE AND NOT HIDE IT INSTEAD OF HURTING CHARLIE.
3. The ending would've ended different like Katie and Charlie ended up together and that charlie supported Katie through it all and they spent their life like that.
4. Katie CAN MOVE TO A CITY WITH TOO MUCH RAINFALL AND LITTLE TO NO SUNLIGHT,
