Personally do not appreciate CinemaSins. I get that it's meant for humor...but it ruins movies for me. I'm not amused by having five million plot holes pointed out in movies I love. Hell, most of the sins are utterly insignificant things nobody should care about. Think of it this way: it's like someone going out of their way to explain a magician's greatest act, thus destroying the fun of it.
But oh well. Most people seem to love it, and I just sound like a humorless snob.
And for those curious, I didn't like the videos before they turned their eyes to KOTCS. I'm not that petty.
