I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
I haven't read the Wimpy Kid Diary series, but I have seen enough of them to know that this is pretty spot on, at least as far as the format goes. Even the illustrations look like they'd fit into the original series.
What's a kid to do when he becomes a zombie? Keep on keeping a gamer diary and try to be the best gamer he can be, even if he does eat roadkill pizza. This was funny and quick, and I'm glad I got the next two in the Humble Bundle. It was cute and cleaver, and although it wasn't laugh out loud funny, I found into the story enough that I want to know what happens next.
