These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Darkness-Induced Audience Apathy: Characters are slaughtered left and right. Anything the heroic characters in the series try to do ends in complete failure while the villains are borderline invincible. As a result, it can be hard for some people to care what happens considering that it soon becomes predictable that anytime someone tries to go up against Kain or his allies they'll automatically die.
Villain Sue: Kain's forces, arguably. They take out any heroes who attempt to oppose them with little to no difficulty whatsoever, sometimes even pushing their wins to ludicrously cheap levels. Especially evident at the end of "Showdown" where Edge is clearly winning his battle against Lionheart and is about to finish him off. One quick fade to black, and when the things clear up Lionheart is walking away from Edge's dead body, the latter having been stabbed.
