You don't understand the grumbles...jeez...
(grumbles)
It's that...
Dude, you're participating in a forum for the expression of individual opinions and ideas - in an electronic format, yes, but no different really than if we were all sitting around a table talking all this "nerdshop" over a few beers (or for some folks, maybe Kool-Aid...) - and you're basically saying 
"Fantastic Four is a bad movie, and that's not just my opinion, that's a fact."
And while I (and several others here) may agree with your ass-essment of the movie, I don't think 
anyone's going to concur with your "it's a fact, not an opinion" thing...
 
Y'know, before you even started dropping all the director-artiste names, I was finding myself flashing back (unwillingly) to the three years that I owned and operated an independent/cult classics video store. 
Most of my customers were cool...some a little weird, of course, just like in comics shops or any other entertainment niche...and most were either college graduates, or college students...Anyway, most of the time it was a stimulating and fun place to be. It was great to be able to talk about Fellini or Woody Allen with other film buffs...and yes, there was often difference of opinion, but it was (as the kids these days ) "all good."
 
Except for the periodic visits by 
Martin. 
Martin always managed to clear the place out by joining the friendly conversations and debates and turning them into arguments. To him, Bergman and Fellini were artists of a gleaming magnitude that no American director could ever hope to match. This, to him, was an undeniable statement of fact. 
Martin spent a good bit of money in my shop, but he probably cost me half as much in missed sales because once he started "getting into it" with one or more of the other customers, nearby browsers would just leave. 
 
I tried to talk to Martin about it, but to no avail.
"If they just had 
more knowledge of what they're talking about, they'd understand," he would say. (Martin was a would-be film maker...He's been "to school" for that.) 
"You can't compare Alred Hitchcock to Dario Argento!" he exclaimed once to another patron, "That's like comparing steak and cow <excrement>."
 
Ah, Martin... I'm reaching for the 
Pepcid as I travel through the memory...
I guess if there was one silver lining about going out of business, it's that I wasn't forced to finally ban him from my shop. 
Which I really didn't want to do, because I actually kinda liked Martin personally. And I agreed with just about all of his opinions.
Unfortunately, for me 
and all my other customers, he didn't consider them opinions.
 
To consider one's own opinion in art or literature absolute and irrefutable is normal. I think those kind of thoughts practically every day about one thing or another.
But to 
declare one's own opinion absolute and irrefutable is to discount and even demean the thoughts and sensibilities of others.
 
So yeah, most people don't really like that very much. 
Even those who may agree with your 
opinion.
 
My heart is beating. That is a 
fact.
 
I just paid the gas bill. That is a 
fact.
 
Citizen Kane is a great film. That is an 
opinion. 
 
Citizen Kane is 
considered by many to be a great film. That is a
 fact.
 
Y'know, I'd like to think that some of this hubbub is attributable to semantics...perhaps a language barrier of some sort...
But whatever...I'm walkin' away from this horse...
They're circling a zebra over on the 
Superman board that thinks 
Quest For Peace was a good movie...
