Let me give you my honest review. And you don't need to see other reviews, I'll cover what you are finding, i.e. a reason whether it is for watching it or not.
Let me cover it in simple points:-
1. It's worth the watch and has a very romantically emotional climax.
2. The whole movie keeps you engaged. There's not a single scene which you want to skip.
Although there will be situations where there's a rush in knowing what'll happen next.
3. Unique concept, one of its type.
4. Even after watching it you'll feel attached to it.
5. Loved it.
I'll give it 4 stars.
You should definitely watch it. You won't regret my advice.
