When it comes to the difference between drama versus horror, within genres? Depends.

If the drama is NOT a comedy, I would generally prefer horror. Why? Well, with the "horror" genre, a lot of stories of the genre may be disturbing as far as being scary goes, but honestly? I think the genre was invented to warn us about the dangers of the unknown; including strangers that don't have a proper background check! Which makes perfect sense! Besides; when it comes to "Baldi's Basics" & "Five Nights at Freddy's"? They're actually quite hilarious!

Drama? If it's not dramatic comedy? Then I feel that it's either nothing special, or it's BORING AND LAME! ("Downton Abbey"? It's just SO boring, unfunny, and with excessive bickering, that I'd much rather watch "Teen Beach Movie", at least it was so bad that it's funny! And at least they were TRYING to be entertaining without trying to offend anyone; the creators just didn't know what they were doing, on that movie! XD)

Besides; I've been through ENOUGH of unfunny drama in my life...SERIOUSLY! If I must watch drama? I'd be best off with a dramatic comedy...and try to look for one that's fairly clean, too!
