I mentioned tales from the crypt keeper a while ago when i talked about stuff getting kid friendly spinoffs in animation (yes robocop, rambo, highlander, james bond, just to name a few and even aliens was going to have a cartoon but it got canned before it was made) I actually gave the show a watch mainly because I'm getting into the original 50s horror comics like TFTC.
I can give credit where it's due the second season actually brought in the old witch and the vault keeper from the other EC horror books The vault of horror and the haunt of fear. Characters who hadn't been seen since 1955 and were never in any other version of the series. And the colors really do evoke the four color pallet limitation older comics had. If YOU wanna check it out I advise sticking to only season one and two though. When it was on cbs the only rule was it couldn't be too scary, no worse than the goosebumps books that were also popular at the time. When it got revived for a third season and moved to abc though it had to adhere to the e/l standards....which basically meant it had to have "educational merit" to be aired on TV.
The earlier season has "morals" woven into the writing but it was not much different than most shows on network weekend/afternoon tv at the time. Noticeable but not too on the nose.
