Audiences don't get comedic-horror films often, let alone, and like with H.G. Lewis' work, when they intend to be trashily over-the-top. Blood Diner is typical in its narrative, and yes, it's simply a polished schlock-film, yet it's near the wacky comedic brilliance of Re-Animator: alive with creativity, laughs, and is gleefully in bad taste. Great party fun if watched with those who also get it.
The occasional moment of weird inspiration (fried batter ball?) does not divert the film from its tedious nature. Like most genre films, its the scrap of narrative plotting (and lame jokes in this case), not the creativity, that drives it when it should be visa-versa. Admittedly a Nazi surf band raises an eyebrow, but this still doesn't live up to its cultist hype.
