I don't know what this other guy was talking about in his review. The estimated budget for this film (as reported on IMDb) was around $400, not $55k. All the cast and crew were volunteers.
For a first try, I don't think this film is so bad. There are some technical details that need work (the lighting particularly bothered me), but you work with what you have. Because of the limited shooting schedule (due to the availability of the primary set) they shot on at least one day when their makeup artist was unavailable (hence the KISS zombies).
The crowbar as a "signature weapon" was a nice attempt, but because it's thin and black it's difficult to see, not like Shaun's cricket bat, Lionel's lawnmower or Ash's chainsaw which are plainly visible and have distinct silhouettes.
