If you didn't cry...
...you're either lying or not a human.
It's rare for me to actually like so many of the characters in a movie but this director was able to pull me in quite successfully, which made me want to keep watching. The story and characters had soul and an amicability to them. I can't remember the last time a Hollywood production has been able to put something so pleasant and heartbreaking together like this. Props to Polish cinema.
