OK, so I just finished the first level and I'm only slightly disappointed. It kind of reminds of Deathspank in a way, in the sense that, it's really just an average/mediocre game but it gets bolstered a little because of the humor/nostalgia.
I also agree with others who posted that the AI is annoying because the enemies just rush you right away, beat you down, and when you get up and fight back, they just stand there and take it.
It might sound like I'm nitpicking and that may be because I was a little TOO hyped for this game and therefore, inevitably let down.
