My Aunt and Mom saw it Sunday, here's what my mom said:
(Keep in mind that they both didn't see MOS)
"Why was Batman so mad at Superman for no reason"
"Why was Superman mad at Batman for getting rid of criminals"
"Where did Batman's robot suit come from"
[blackout]"Did you see Wonder Woman drop the magical dirt on the casket at the end? That's how Superman comes back?"[/blackout]
That last one made me lol, she was being serious too so I had to explain it. She said it was a good movie but she was left confused on a lot of things. She said she'll watch it again, along with MOS when they release the 3hr version. She even knows they cut a lot of things.
Now I wait for my dad...
I took my 8-yr-old son for the second time (the first time he sat next to his grandpa - and the grandpa fell asleep, so he had no one to direct his questions to). It was his idea to do this the second time, I think he wanted my commentary on it. Unlike your mom and aunt, he saw MoS about three times and loved it (begged his grandma to buy the shirt). These were his comments about BvS:
(On the world engine)
"Oh look! Wow, this movie really makes it look like it's continued from Man of Steel."
(On Batman's branding a man)
"He also has a Superman logo on his Batarang"
(On the bathroom scene)
"Why is Lois naked in the tub?"
"Eee! Why is Superman jumping into the water with his shoes on?"
(On the crypt scene)
"This is the scary scene right? It's so loud."
(And when Bruce wakes up)
"Who's sleeping in his bed? Is it Alfred?
(On Lex taking his first walk towards Zod's ship)
"I don't like this music"
(On the congress scene)
"What is Granny's Peach Tea?"
(On the Knightmare scene)
"What are those flying things?"
"Why can't Flash come out of the time warp?"
(he'd been watching the Flash series with Grant Gustin, and that version of Flash has been walking in and out of time warps like nobody's business)
(On the Batmobile chase scene)
"Why is Batman killing people?"
(On the WW photo)
"Wow Wonder Woman also has her own song?"
(On the final scene with Lex)
"Why is he saying 'ding ding ding'?"
