Yeah, if that is what for him qualifies as "terrifying and hearbreaking" by that same measure every time Wile. E Coyote plummeted to the bottom of a cliff in a Road Runner cartoon it was "horrifying and heartbreaking".
God lord man, and he calls himself "mature"
This guy thinks that Spongebob Squarepants is a more "mature" form of entertainment than lets say Roots. This is a man who thinks MLP-FiM must be mature, because he does not see any other reason for people over the age of 10 to watch it, ignoring that (autism aside) the more likely reason is that some think the cartoonish humor and cute characters are worth watching it once in a while. Are you really that surprised that he looks at that scene and acts like one of these manchildren who write on tvtropes how they cried over the fact that Strawberry Shortcake did not have a good birthday in one episode?
And just to get a few dumb/off-topic ratings extra, he thinks that is the most scariest way how some villain died in Sailor Moon? My sister forced me to watch this show as a kid a lot and we grew up in France, where this show was actually shown in an uncensored manner (so unlike the average American, they did not beat around the bush that two characters are lesbians.). And I can remember quite well that one minion got disposed the following way: Being eaten alive by nanites. Granted, it was not as if the show would showcase how the girl was eaten up/out from the insides by microscopic little robots by letting us see her flesh being devoured until the skeleton remained. But I consider that idea to sound scarier than someone (literally) pulling the plug.
Last but not least, he does not like it when villains are killed off? I am admitedly a fan of villains being redeemed over killed (as long as they did not do something that really crosses any moral line) but coming from the guy who has no problem killing off NPCs in a Skyrim game for making stupid innuendos by going Spanish Inquisition on them AND admited that he had power fantasies of killing all his fellow classmates at school, I say fuck you. Especially towards the fact he thinks he has matured enough to the point that he does not want to see characters die. As smeone mentioned, character death can not just be an excuse to get rid of someone, it can be used for good drama. And sometimes there are just characters who need to die, because they are too much of a monster to remain alive. Not that Dobson would know anything about it, cause this guy has less actual villains to offer in his work than fucks Brianna Wu gives about him.
Just look at his comics. Not one single consistently, cunning or funny villain. Only unintentional villainous heroes at best.
If you don't want people to die, watch comedy shows, or baby stuff like Caillou or Dora. Watching a (children's) drama where teenagers with superpowers fight against evil? Yeah, sometimes evil people kill and get killed.
And sometimes good people to. Heck, the entire cast of Sailor Moon died at the end of season 1 and at the last season. At least seeing how he does not like to watch animated characters die, I can now understand why he hates NGE.
... God, I so want to force Dobson now to watch Berserk while he is stuck in a chair Ludovico Style. Can you imagine his overall reaction at the Eclipse Event?
