I was specifically referencing your logically-sequenced approach to it when I was saying "I believe a consensus has been reached."
In reality, I'm still a bit confused from the start, I don't recall if I was referencing "entire genres" to discard them.. I did mention "a bad movie is something different to every person".. I know this is BITOG, where things can be discussed to the point like one may feel like they are listening to a dissertation at Harvard.. or giving one.. yes, you did try, OVERKILL. lol.
But I'm not sure I would call the Kenwoods you buy at Radio Shack "speakers" or.. what did you reference? Panasonics? Maybe I can interject.. GPX 4 LIFE! (I have had quite a few GPX units as a teen and pre-teen, including boom boxes that RECORD!!! Right in the speaker!!! lol, and knock-off Walkmans. Discmans were out of GPX's league for me, which is why I got a.. Fisher. With 10 second buffer!!!)
But for real though, I think your post is why I say there IS consensus.. and that is, that, it is subjective, different for every one, and I would agree there are some criterion. (Such as, overall acting.. which is subjective.. but perhaps more overall production. I do recall Star Wars initial production quality being questioned, though I'm the ultimate "A piano is a box of wood and strings" person on that, thanks Matt Damon in The Departed, can not really stand that guy. Think James Earl Jones visible through a visor. Which would make me laugh, and add to it, for me, actually, lol. As to Matt Damon.. That's not acting, that's being a natural jerk LOL. It is more realistic if it is natural. Not acting.)
