Hello Steven,
your logline reads like a classical, well-known plot, which isn't necessarily bad of course if you do it right.
I've also seen your title quite often before, so I checked it. Here's a link to imdb's exact title search
https://www.imdb.com/find?q=trick%20or%20treat&s=tt&exact=true&ref_=fn_al_tt_exAgain, this doesn't mean a lot if the execution kills it, just be aware that others, filmmakers etc. may also know this general selling package you offer here. Just food for thoughts…
"looks through the eye of a camera"
Do you mean a viewfinder or a display?
Imo, if you write a movie, this visual "idea" of yours should be technically correct and clear.
The old man carries a mysterious bag outside part feels truly dusted.
Okay, read it all…
It's too generic. I mean, few of the first 10 pages is economically told regarding its true visual experience that'll be on screen. The picture is just slow while the dialogue is overwritten for what is. Then I hoped for the huge third act punch that may have saved you with an advice to drastically cut it - but it just went along.
I liked some of the characterization and the language of the boys felt overall authentic.
However for thirteen plus minutes, I'd need more specific story characteristics, something fresh, maybe surprising, to lastly feel entertained.
It's a solid presentation but not the kind I'd personally call enough.
All best
Alex
