I can only say from the demo that I didn't enjoy the shooting although I am interested in the characters stories and the visual style. 
 
The enemies seemed to take to damn much since I used a shotgun at close range and the guy got up and kept shooting .

Not a bad game and fun for a playthrough. I'm glad I only borrowed it from a friend after he had beaten it though, I would've hated to blow $60 on it. The visual style was really cool and some parts of the game were just plain old bizarre.

its kane and lynch 2.

It's a video game.

Well like the first one.  I generally didnt care for any of the 2 characters.  The action is decent and the whole cell phone recording effect is awesome.
 
Havent finished the last chapter yet,  so far it's just so so.

The campaign was super-duper short. (finished in one sitting) but it was good and "gritty". 
 
The multiplayer is tons of fun.

Kane in Lynch 2 is a solid shooter that has some flaws, but also has a very unique aesthetic and the characters are interesting enough to make you want to stick with the game until the end. Granted, it doesn't take you long to get there, but the journey is an enjoyable co-op experience.

I only played the demo, but I liked it. Not GOTY level certainly, but an interesting visual style paired with even more interesting characters and story seems good to me. 

Looks nice, not interested in buying.

I love it! Single player was way too short but, boy, what a ride. Dog days is without a doubt the most intensive game i've ever played. Multiplayer is a blast too, especially Undercover Cop. I should say though, if you're not going to play it with a friend, you probably should stay away from it. But if you have someone to play with it's a no-brainer.

It is definitely limited but IO done better with Dog Days. There is a certain feel that is fulfilled every time I play this game, violent and grimey with a Hollywood flair.

I think the "deliberately looking bad filter" and shaky camera is great
it shows you that you don't really need crazy detailed/advanced graphic technology for a sense of realism
 
oh and, Kane & Lynch 2 is probably the only western game that got the Chinese words right (in terms of both writing and meaning) after GTA4 :D

Haven't played the full game, but just seems like an average third person shooter from a gameplay perspective.
 
I couldn't even get through the demo on my PC, the aesthetic crappiness bothered me a lot because it just felt like I was playing the game on a really crappy computer at a really low resolution.  I know that's the point, but I played games on a shitty PC for 3/4 of my life, I don't really need that anymore.  The shooting didn't impress me either for the 3 or 4 minutes I actually played the demo.
 
The multiplayer stuff seems interesting, but I doubt it would be able to hold my interest for very long.

Ill pick it up when its cheaper, i just couldnt pull myself to buy it after the reviews it got, ill save myself for mafia 2.
