My Wife is a Gangster

Just finished watching My Wife is a Gangster and I don't really know what to say... Eun Jin is a legendary gang boss for her shocking skill with a knife, despite being female. But even her menacing threats can't help her elder sister when she is taken to hospital with cancer, little hope of recovering. However Yu Jin (Eun Jin's sister) wants to see some things through before she passes away. Just a small request for her sister. Get married. So her underling, Romeo gets his girlfriend to glam her up and they send her on a blind date, it doesn't go according to plan. But not all was wasted as Eun Jin then finds Soo Il, a push-over who was stupid enough to agree to marry Eun Jin. Now they are awkwardly married with lots of abuse thrown at Soo Il. That would be the end, if Yu Jin wasn't so spoiled. Unsatisfied with her sisters awkward marriage, she now confides to Eun Jin that she's always wanted kids. So Eun Jin literally forces herself upon Soo Il to try get pregnant as soon as she can. Eun Jin gets successfully pregnant and now she's set the task of looking after the unborn while being a gang boss.
 Unfortunately, Yu Jin dies soon after and Eun Jin has gang problems then when Soo Il finds out about his wife's occupation, things can only end badly! But I must admit the end really confused me, because they suddenly bought in these things which no one mentioned before and it's really rather unclear. It was rather anti-climatic actually, sure there was a giant fight scene, but the plot just stopped. No conclusion or explanation, just the end credits. There's a lot missing in this film, like some humour, some romance, a plot and a conclusion. But the rest of it was (almost) good!
Well at least the actors done a good job. What's that? They didn't do well? Every one just looked gloomy? Yeah, I suppose your right. They did lack a certain pizazz. Well, maybe they were supposed to have the same facial expressions throughout the film, but it did bore me.
Although maybe it's just because most of the characters and gang members who have had they're personality sucked out of them, they're supposed to be boring! But that doesn't work for Soo Il because the man who walked into a fight only to be knocked out by the same woman he thought he was protecting should of been SO much more exciting. So why was he so boring too? Hm? The only character with any colour was Romeo, always trying to look big infront of his new recruit, singing in front of his enemy then taking his girl out to propose to her. The film should of been about him, it would've been so much more exciting!
But it wasn't about Romeo, it was about Eun Jin. And Eun Jin is such a boring person! The plot, had quite a nice section somewhere in the middle but was mostly bad. I easily lost track of who's who because every one was so boring. Also, I don't know how to tell you this, but the fight scenes looked so awkward. Honestly, I couldn't say I enjoyed it...
