-this one started out promising. I was impressed by the boxing scenes in the first episode which were (both, the training scenens and the actual tournament scenes) rather realistic and well done. I was hoping the drama would stick to the idea of keeping the fight scenes realistic to some degree. Sadly that was not the case. The further the drama progressed, the worse the rather elongated fight scenes got.
Let me put it like this: yes, a real boxer can take a certain amount of rather strong blows to the head and take it. But also this is limited. Someone who is particularly not a professional boxer, like the main villain Kim Myeong-Gil for example? It is rather ridiculous that he gets full force blows to the head coming from a professional boxer about 20 times in a row, and he just gets up and hits back and even runs away. Plus the villain is in his 50s. Someone not used to these blows and that age? Gets one, maybe two strong blows and is knocked out cold - or actually dead.

- similar unrealistic scenes sadly with one of the main characters - Hong Woo-Jin. In the really brutal attack he suffers in the middle of the drama? He is beaten, he has a severe heavily bleeding wound (or several) in his abdomen, stomach etc. , he is left there in a burning building with heavy smoke he inhaled given he was still breathing. He would have been dead there. He gets to a hospital nonetheless, again is bleeding so heavily no one could survive it, - and survives. And even more unrealistic is that someone who had suffered these severe, extremely damaging injuries, can get as flexible, fit and strong again as shown later. Even if, by a total miracle, he would have survived these catastrophic injuries he would not have been able to stand multiple super strong opponents fights like shown afterwards. In fact, if he really had survived he could have been happy if he after a longer while would have been able to walk straight, to go to the loo normaly, to use the parts of his body (muslces, tendons etc.) that were actually crashed and destroyed to a decent degree. Never would he have been able to train like a bodybuilding maniac with full power and flexibility.
(and to add that too: none of both main characters would have any teeth left, neither their small, straight beautiful noses. Their faces would have visible and lasting heavy damage, Woo Do-hwan's character already after the extreme face headbutt he receieved from that troll guy in the beginning. If happened as shown, all teeth would be broken out, nose would be broken)

- the plot started out ok, showing the mean business of loan sharks and how they terrorize people which actually really happens in South Korea. It later got a bit confusing as to why certain things happen or don't happen, which was gilded with even more rather violent action scenens and fights. I have to mentione 'my name' once again, which had heavy fight scenes as well, but they were comparably brilliant, stayed at least realistic to some degree most of the time and didn't need to be so excessive to overshadow weaknesses in the plot as there, the plot was strong and intelligent.

-Woo Do-hwans character Kim Gun-Woo...oh well, someone who has witnessed the sheer evil of what happened to his mother, then to the granddad and his then best friend? Someone like that is not still like a naive puppy most of the time, it doesn't really make sense to me. f you have seen such things, survived them and decided to take up the fight against highest organised crime,you simply can't be like a 5-year-old good boy most of the time, it wouldn't work.

- I personally didn't feel any real chemistry between the characters, especially the girl, Kim Hyeon-Ju, seemed strangely artificial and 'created' to me.

I was waiting for this drama eagerly as I really liked Woo Do-Hwan in 'the king, eternal monarch'. In 'bloodhounds' now he got an impressive body for the drama, and it's obvious he had real boxing training. Sadly I didn't feel his character was real, due to the rather mediocre plot, and rather artificial connection between all the characters.

-I also thought it was just too much violence at some points hiding the weak plot, - all in all, it couldn't convince me, I didn't like the whole 'mood' in the drama and wouldn't feel like watching it again.
