First and foremost - this is an action film. Is there romance and emotional delicacy in it? Yes, but it's still an action film; there is a lot of fighting. If you like action, you're probably going to like it, if you don't, then it's probably going to drag. If you're on the fence either way, I'd ask you to give it a try, because the fights are well designed and interesting to watch, sometimes rapidly switching from guns to knives to fists and back again, keeping things dynamic. If you're particularly squeamish though, maybe give this a pass, or bring a friend to tell you when it's safe to look; I know it would have my mother clutching her figurative pearls if she didn't faint from shock.
Although the plot is very simple, and isn't going to bring you any great surprises, the film, from the cinematography to the actors, definitely puts all the effort in to give emotional depth to the available scenes. There is a maturity to it, a solemnity and bittersweetness that matches the level of violence it contrasts; this is not a cute and lighthearted saccharine romance with some punches thrown in, it is an absolutely, desperate against-all-odds, tooth and nail fight to see the sun rise one more time: love and devotion is just the seasoning to salt the wounds. The acting is great; you believe their relationships, their fears, hatreds and sorrows as well as their joys and cares, even the characters who have little screen time, or do not even speak at all (there is a character who seems to be mute/deaf, I'm not sure which).
It did have some weak points like them just jumping to blood transfusions way too quickly, and always life-threatening volumes for no apparent reason, and we don't spend a lot of time getting to know the whole family - but maybe that's just the director showing mercy so you aren't an absolute emotional wreck by the end of the film.
The fight scenes in this are amazing - bloody, extremely brutal, and equal parts tragic and badass. They may not be the most realistic (not that I get into that many shootouts myself, but these guys are definitely wearing bullet-resistant plot armour), but they really pack a punch, and honestly they had a fair bit of flair without it feeling wildly impractical (imo) like the parkour that was integrated like butter. The longer fights also feel...intelligent. Not that the characters are pulling any Einstein moves, or even that they don't do dumb things sometimes, but the struggle isn't simply brute force, you can clearly see the characters trying to out-maneuver each other as they lose and gain ground; it's often unclear who will win or lose, even in a fight where one side may seem to have the upper hand, things can go back and forth in the blink of an eye.

All in all, I think this is a well rounded action movie that balances it's intensity and brutality with moments of calm and softness, gradually ramping up the stakes from the first attack to the final battle, interspersing each instance with a period of peace for the viewers and characters to recover before raising the stakes for the next conflict.
