Well, first off, several of the episodes imply disturbing things about the world wherein they are set.
Sure, the Bad Santa of "And All Through the House..." murders the traitorous wife who killed her husband and tried to hide the evidence. At the end of the story, he's still at large.
Not to mention, what happened to the daughter of the woman after that night? Sure, the Crypt Keeper tells us that the killer didn't hurt her. But did the daughter grow normally, or suffer mental illness later on?
The twist of "Beauty Rest" is that the murderous Helen is herself made the winner of the beauty pageant. This pageant? Miss Autopsy 1992. Such a contest being held, not to mention its large audience and one employee's comment about how they should "pick them off the streets" like in the past, is the real Nightmare Fuel of the story.
"Mournin' Mess", one of the few stories to feature a Karma Houdini villain (or in this case a villainous group) where ghouls pick off the homeless while posing as a homeless support group. By the end of the episode, given that they've eaten the guy who's discovered the truth, it's implied that they're still active.
"You, Murderer" shows that at death, at least for Lou, results in an And I Must Scream state where you're trapped in your corpse, still able to see, hear, and feel pain. If Lou's final words in the episode are true, then Death itself is a Fate Worse Than Death.
More immediately, it means that Lou's own murderers aren't just dead at the end, they're consciously trapped under the car in the grave they'd dug for him!
Not to say that Mildred didn't deserve her fate at the end of "Korman's Kalamity", but it looks like Korman's new life with Lorelei might be cut short if he's gonna have to explain why there's blood (and his wife's dead body if the Mildred monster didn't eat it or something) in the Tales from the Crypt office.
"My Brother's Keeper" ends with the creepy implication that Frank is going to act a lot like Eddie did. And considering Eddie was crude, abrasive, and not above murder when something went wrong...
"Top Billing" has some rather nasty Fridge Horror in the twist ending. As if the reveal that the down-on-his-luck actor was really auditioning for the part of Yorick's skull wasn't bad enough, it turns out that Nelson Halliwell and the others are really patients in an insane asylum where the entire staff has been killed. While the episode ends with police coming over to take care of the situation, the very last shot is of the hapless actor's discarded face being carried off by a ravenous dog, which may end up developing a taste for human flesh!
Speaking of which, the restaurant in "What's Cookin'," whether it's called "Fred & Erma's" or "Farley's Flame-Broiled,"remains open for business! So who'll be tomorrow's "black and blue" or "slab of moo"?
