No, you're allowed to have an opinion. I'm not really sure what I think about it, though.
that trailer is kind of more of an artistic melting pot of carnage than an actual setting the tone or setting the narrative type deal - i guess it might work for some people but it didnt offer me anything really particularly interesting or unexpected... if it wasnt a marvel film i probably wouldnt see it
im watching the trailer and it's cool and stuff but there's nothing really in it that makes me really feel like i need to see it - i will see it but it doesnt make me feel hopeful about it...
maybe i wont bother seeing it in the cinema given all the films set to release near it...
sicario 2 releases the week before, Jurassic world 2 releases the week before that, incredibles 2 releases the week before that, oceans 8 releases the week before that, solo releases the week before that, deadpool 2 releases the week before that...
and 2 weeks after it releases there's Alita which i knew nothing about but the trailer looks incredible, and mamma mia 2 also releases that week (the first is my guiltiest but not-guiltiest pleasure), the week after that is mission impossible 6 and the the predator hits in the first week of august
i might not see all of those films in the cinema but there are at least 8 releasing around that time that i will see in the cinema ahead of ant-man - so if i have to choose between it and most of the releases around that time then it might be one that i skip unless i see it gets reviewed well or word of mouth suggests its absolutely must see
the May-August release schedule this year is insanely full and i think it might actually end up contributing to a fall in box office for almost all of the big releases...
Deadpool 2 has the advantage of coming out first of all the summer releases and being 2 weeks away from infinity war (which will be by far the biggest box office draw of the 2018 releases) but outside of that i think most franchises are going to be slightly disappointed by the box office for their big hits...
