This is deffinitely worth all 10. I never would've thought that I could like a drama about people in their 40's but after watching this I can (without a doubt) say that I was SO VERY WRONG. This is realy one of the best dramas I've ever seen. From hilarious scenes to heart breaking ones - everything was outstanding. The story about four 41-years-old men might seem boring and etc. but it's not even similiar to what you might think at first. For people to stay such a good friends for more than 20 years seems impossible but these men take friendship to the whole new level. From playing starcraft together (LOL) to leaving everything because something happened to one of the four seems so amazing. And even from the screens they make you wish to have friends like that because it feels like with them you don't need anything else. The females of this drama are also very strong so it's even more amazing. And there aren't any anoying ones (well, at least for me there weren't) that everyone hates. They are ALL fantastic characters. This was the first drama I've seen that had prologues at the beggining of the every episode,too. They are so amazing to watch. You just laugh and you can't stop laughing. It's one big LOL. xDD Oh, right there were also guests like SooYoung and YongHwa. ^. ^ So, the last thing I want to say is that this is REALY amazing drama and you should definitely watch it. It's realy good if you want to laugh and laugh, and laugh again ;) ;D
