Painfully in example sentence
Written, directed, shot, scored and edited with an appalling lack of flair and finesse by the singularly talentless Rick Sloane (who later disgraced celluloid some more with the absolutely atrocious "Hobgoblins"), this horrendously ham-fisted attempt at a slasher spoof strikes out something rotten in every conceivable way: the excruciatingly lethargic pacing, the painfully static, grainy cinematography (there's a stinky surplus of drab master shots featured throughout), an annoyingly droning and redundant hum'n'shiver synthesizer score, the flat (non)direction, a tediously talky and uneventful script, the groan-inducing sophomoric sense of lowbrow humor, the bloodless murder set pieces, a pitifully unscary killer (he's just some wrinkled-up old guy in pasty make-up), the uniformly obnoxious and unappealing characters, a dissatisfyingly abrupt ending, and lifeless performances from a noticeably uninspired cast all ensure that watching this schlocky swill is about as fun and rewarding as eating rancid raw eels drenched with sour vinegar.
