David Decoteau makes bad horror films with the build quality of a Trabant, and the acting quality of Lower Muckwallop's village Christmas panto. His films are bought for one reason the flesh. If there is an excuse for a cast member (usually a male one) to remove clothing it's used.
The plot about people being dead and not realising it could have produced a better film. Sadly here it doesn't. What you do get is effects that are just silly, long softly lighted shower scenes (of male cast members), and an extra that tries so hard to be in shot he almost starts jumping up and down.
That all said it is very funny (though not by intention).
