I don't think I get it?

i thought the same thing. it didn't make sense.

The end was a bit of a mess. They didn't stick the landing in the last 3rd

I genuinely don't think the movie makes sense.

I don't there was a coherent vision here. I can't help but feel that maybe Peele started with some ideas and scenes, and the follow up writers added filler, but without really taking into account how it all comes together. So you end up with seemingly conflicting ideas that's not quite subtle enough to leave it up to the viewer, but not explicit enough to have some things make sense. So it just feels like a hodgepodge of ideas that wasn't quite edited. Like the Last Jedi, which feels like it went through script transformations so you just see disparate pieces all over it.

Basically anyone who was wrongfully murdered became a Candyman. The Sherman angle was confusing because he's the killer here and not the OG Candyman and he was lurking about even before the events of the original so it's like, where he was during all that? They tried to add to the lore while making it disjointed too. Burke was just fucked up in the head and ended up embracing a tragic event that once startled/disturbed him (how typical) and felt the need to replace Sherman with someone new, so he picked Anthony to take on the mantle due to his connection to the OG Candyman. However, the REAL Candyman showed up at the end and said "OH NO, HOLD MY WATER" and that was it. Ugh, just a mess of a story.
