Firstly this is not your usual love story drama, so if you're not okay with more realistic movies, you shouldnt watch it.
People nowdays are so used to dramas with the perfect ending, with all the "They Lived Happily Ever After" that they forget real life is not always that easy.
This is one of the good things about this movie, they tried to be more REALISTIC.
I got a lot more to say but don't want to spoil anything.
All i gotta say is: watch it if you're okay with realism.

I do think all the "fantasy" scenes were kinda too funny to be taken seriously, they could have done something better about that tbh
