Southpaw: dead wife, daughter taken away, boxing, blah blah manpain.
Jurassic World: I'm pretty sure I'd get more enjoyment of out re-reading If The Velociraptor From Jurassic Park Were Your Girlfriend.
Batman v Superman: Dawn of Justice: holy shit it's actually worse than everyone's jokes about it.
Pixels: here I was, desperately hoping for something fun, I actually laughed at the appearance of Pac-Man, and then boom! Adam Sandler. GAH.
Fantastic Four: it might be the contrast, but this didn't look actively terrible? Not, like distinctive or necessary or anything, but not actively terrible. (It was this one; I gather others were different.) I still roll my eyes that they couldn't cast Sue as a black woman too—I mean, yes, it's absolutely possible that she and Johnny are biological sibs, rather than adopted, but actual literal visibility matters. (Yes, I'm aware about the potential relevance to Sue's powers, but still: cast a very-light-skinned black woman if that's what you're going for.)
Tomorrowland: this is the second trailer I've seen for this, and at least it gives me way more of a sense than the first one? I'm still unsure about it, though.
Ant-Man: well, this trailer was more appealing to me than Guardians, which pisses me off because it'll probably do just as well and I don't want it to, because of (presumed spoiler) and also because I still resent its existence.
