I have to say that the fandom's reaction to Crowbcat's excellent video has been interesting to watch unfold over the past couple days, to say the least. I get the feeling that he's pee'd on the parade, so to speak, and is now bearing the brunt of it. I think reception is split squarely down the middle, between those who acknowledge the content of the video and either agree or disagree with its point, and those in denial of the content of the video, who are attacking anything peripherally connected to the video other than the video itself in an effort to have it omitted from discussion.
I've seen countless attacks on the uploader themselves, many attacks on RE4 fans, disproportionate hyperfixation on the metadata of the video (i.e. the title and description) revealing a so-called bias, a mysterious epidemic of chronic boredom elicited by the video so bad that the afflicted can't possibly bear to watch it, and extreme scrutiny of the video's audio levels to a point of wilful ignorance of all else. It is almost as if the 37 minutes of footage itself were a total blind spot for many. I wonder if there's some kind of Freudian pathology at work, perhaps a case of repressed disillusionment that people are reluctant to confront.
Jonipoon, although I disagree with your post, I appreciate that you engaged with the meat of the video and offered something to think about. Personally, I've always considered unjust comparison to be a myth typically invoked when a given comparison does no favours for the party invoking it. Where two things exist, they can be compared. Sometimes it's not worthwhile to do it, like in the case of a broomstick and a television, but nonetheless it can be done because different objects possess different properties and purposes which can be compared and contrasted. With respect to Resident Evil 4 and its remake, I would have thought that if the two were so sufficiently different as to be incomparable, then surely the new game could never have passed for a remake of the first, right? After all, what would be the point of releasing and marketing it with the title "Resident Evil 4" if it did not resemble the original game enough to be recognisable as or comparable to it?
As for the general questions about the point of Crowbcat's video, personally I dismiss them out of hand as daft gaslighting. The value of a comparison between an original and its remake is self-evident and needs no formal justification. I doubt very much that anybody would ask such questions about the point of a comparison putting a remake in a more favourable light than its original. Honestly, I would sooner question the purpose of questioning the value of the video, rather than just engaging with the comparison and learning something from it.
