I'll admit I'm extremely excited by the film and that, of course, reading negative stuff is not something I enjoy but I'm puzzled by slugzilla's account. Needless to say that his over the top hate of Josh Boone is making anything he says a bit hard to believe. I'm not buying it, I'm not buying the early iteration, supposedly, of the film considering that Boone has been talking about and working on the film for years, as far as I know, it's his & Knate Lee (co-writer)'s baby, they came in with that vision & intent to make it a horror film (which by the way, if you actually read the Demon Bear run, makes perfect sense, real nightmarish vibe there), we all know the story of them making some kind of giant comic book using panels of the comics to show their vision.
So that fantasized, light, fun version?! Where is that coming from? Slug's aversion to the horror vibe clouds the rest of what he says as well, this is Josh's vision, you don't have to agree with it, and if some higher ups really had a problem with that, they'd have said so early on and would not have let him make this.
He's been adamant about what this is for years. Now, Boone supposedly being a jerk?! There has literally been nothing out there to that effect, I don't know him personally but everything about him & his past experiences show a decent, kind fellow. John Green (The Fault In Our Stars, Paper Towns, Looking For Alaska, etc for those who don't know him) is I believe a great judge of character, and everything about him being involved, on set, of TFIOS along with Shailene Woodley, Ansel Elgort, Nat Wolff, Laura Dern, etc, shows a real positive experience. If you look at Boone's & the actors' social media, I highly doubt there's been any issue with the cast.
I think the main problem with slugzilla's account is him saying he was working as a caterer on set, was that a joke or was he serious? Everything he said pointed to him being involved in the actual production of the film or in a post production capacity, especially when mentioning multiple people supposedly told Boone that his approach was wrong, that everyone he talked to who saw the film didn't have any positive things to say.
Or maybe Boone was just a jerk to the "little" people, who knows, or maybe he was in a bad mood, who the f knows.
What he's saying, if he truly is a caterer, makes no sense. He cannot possibly know any of these things unless a producer, an actor, a camera guy or whatever, actually working on the shoot (ie involved in the making of the film), has been blabbering while picking up his/her food. I highly doubt that anyone in that capacity would also willingly tell him any of these things.
Even ManaByte said on Resetera that two people who've seen the December screening, told him: 1st one: screening went well, 2nd one: that it was pretty awesome. A redditor also said he supposedly saw the film at that screening, that it was a cross between X-Men, Insidious & The Breakfast Club, he really liked it and that it was also very funny.
Couple that with the CCXP footage shown of all of the kids taking a lie detector test to learn more about each other:

There was also a more detailed breakdown by Omelete I think?! mentioning how the footage had a very youthful energy and was funny. So is the film really that dark or has it been exaggerated?! Those things show it'll also be fun.
Not to discredit Mana, but Jeff Sneider is as good as it gets in terms of source, if he says the screening went well, but not great, and they want to amp up the scares, I buy it, it does contradict the other reports that it's to make the film lighter, although amping up the scares doesn't necessarily mean make it even darker. So why the discrepancy? bizarre to say the least.
