It's a quite complicated to understand but it's still worth to watch, first thing it does not ending which usually is like they lived happily ever after so if you are looking something like that then it's not the place to find. It's a beautiful love story which makes you smile but also have a big twist that left you shocked.

It was well executed, acting was good it is far better than other movies about time travel but it also left with many unanswered questions so it does have many plot holes. It's definitely a tearjerker that will let you cry until the end and you'll get a unsatisfied ending also, but it still worth to watch because it's like true life we don't get everything as we want.

I'll definitely recommend you if you are not softhearted person, it's a heartwarming and tragic story but it will also give you some pleasant moments!!
