With regard to Hulk surviving BB's scream...
I think what we have here was the writer's poor attempt at the Hitchcock effect: suggest the event, then let the audience fill in the details, getting them more involved in the story and making it seem more real.
"There's been an explosion on the moon--chunks of lunar rock breaking out of orbit." It is not clear if this is from The Scream or the previous whisper, as the latter shows rocky debris going skyward.
"He withstood Black Bolt's voice." I would think that if Strange was referring to the Whisper, his statement would've been worded somewhat conditionally (eg, "He withstood Black Bolt's whisper; let's see if he can handle his voice Big Time"😉.
Together, the two suggest Hulk withstood BB's full power (and showing us that much, at least, would've been nice), but there is no lightning in a bottle here.
I also wasn't crazy about Strange's reasoning for not doing anything. First of all, if he could send Hulk to another world, why didn't they just do that in the first place? Why bother with a ship? Secondly, isn't there about 1000 other things Stevie could've done?
Still, I enjoyed this.
