The most useless qualifier of anything fiction is "boring". It has no meaning. It's pointless. If you say "A is boring", is means that you weren't engaged by A. It's as informative as saying that sky's blue. Wow. Much eye opening. Very deepness. I think GTA is boring. And RDR is boring. And Call of Duty is boring. So what if twenty trillion dudes think otherwise? And so what if I'm not bored with 2001: Space Odyssey? "Boringness" qualifies nothing but an extremely surface level evaluation. If I don't care about you, I don't care about what bores or not bores you, whomever you are, unless I already care about you. Even statistical output is meaningless here. It's purely, entirely a matter of taste.
Call something "boring" and leave it at that is the best way to piss me off to no end up to and including writing this tweet.
