I quite liked this, even if it was a bit dragged on.
You might cry (I did), and it does have an open ending, up for enterpreting. I did Google it after finishing, and what some comments said made sense, but I won't reveal any more here.

This is kind of a typical role for the ML, and he does it well. Not exceptional, but better than "OK".
I liked the FL in some of the other roles I have seen her in, and this is also a bit similar character to some of her other ones. It is the same for her as for him: Good portrayal, but not "wow".

The story itself doesn't romanticize the depiction of the firefighter profession, but shows some of the struggles that comes with it, both for the firefighter and for those around.
I kind of wish they had kept the story a bit simpler at times - some added plots for tension/drama could have been avoided, in my opinion.

It does have some similarities to other dramas in the same genre (first responders/military).
