both have similar meetings of the main paring.

A Beautiful life ends up being a lot sadder than My Sassy Girl, but both movies are rather endearing, sweet and fun.

at the core of both are a structured search for justice even if you have to go a little outside the law to find it.

While Cold Eyes seems more cohesive thematically with a believably menacing antagonist, The Beast seems a bit less heavy handed about the idea of Big Brother always right behind you.

they feature men who want to be part of a family, even if that family doesn't know it. These men may not go about it in the healthiest manner, but they're flawed and are doing the best they can with the tools they're given.

The action isn't half bad either.

Both are about a man using his smarts and shooting skills (bow & arrow in one and gun and martial arts in the other) to rescue a girl.

Both men are also seeking redemption in some way which makes the quest and need to rescue the girl a quest to preserve what little faith/hope in the world they cling to.

If you like action and heart, you'll probably like these films.

With SG you start with some ridiculously (and slapstick) funny moments, and later more spy thriller and action moments.

With TMFN you get some heart at the start and more and more action.

They're not very similar, but they're both entertaining.

There is a similar will they or won't they and "fate" theme.
Acting is solid.
If you're up for a couple of hours of yelling at the tv and ready to root for your favorite match, then check it out.

it's also a office romance with an older woman and younger man. Their chemistry is amazing and there are lots of laughs once you get past the extreme silliness of the first two episodes.

Office girls had a similar feel. Some silliness, some cuteness and entertaining actors.
