Questioning Queries through Wolfman

Husband sent me a trailer. Wolfman.

At the end, my thought was... I wonder if this is what you're not supposed to do in a query. A trailer for a werewolf movie that doesn't look like a straight-up horror should be something I go all gaga over, but this one I watched the beginning thinking blah blah blah, any more history I should know before I watch a trailer?

I'm not an agent to know for sure, but I know I'm tempted (was tempted since I've stopped querying for a while as I write novel number two) to tell the backstory, the reasons behind the current story. How the main character got to where she is to help explain the difference the story is making in her life. But watching this I wondered, do they really need to know? Did I really need to know here?

In this, it just gives me a feeling of disconnect from the story rather than the connection I need to make me anxious to see it. I wondered what drove the one son away from the place and the father, but left the other son behind? Was he angry at his brother when he left too or was it entirely filial? Did the other brother refuse to leave? Why did this one come back? I'm wondering about the backstory, not the current issue. I don't think that's the goal here or in queries.

So my answer would be that there's a good chance none of us need to know. If you're a writer who has been querying, look at your query. Are you telling back story or are you telling current story? I'd go look at mine again, but I'm determined to ignore that story entirely until I've finished book two then read it again to see if it needs more edits using the amazing experience I will have gained from writing the second. Good luck to the rest of you!
