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.
Rooting for the Empire: At least in the original. Terry O'Quinn's charming and likable performance can make the viewer forget that his character is a crazed serial killer. The Cinema Snob even pointed that out in his review
Squick: Stepfather III used actual plastic surgery footage for when the stepfather gets his face altered.
What an Idiot: Susan, big time! You'd expect her to notice something's off with her fiance when the warning signs came up, as obvious as a blaring alarm, but nope. She just swats them off. It's to the point where you'd want her to die.
