It's fine - a pretty meh love story which is saved by the chemistry of the lead actors. I thought the non-linear timeline added something and didn't just feel like a gimmick.
The most interesting part was the idea of how you want to be remembered after you're gone, and I loved the final scene for this, but it felt more like an afterthought at the end of the movie which was a shame
