I can only describe this movie as off and it seemed unfinished.
Such a strange movie. The dialogue, the motive, attitudes, everything. Especially the very odd timeline jumps.
Then the ending, it was just so peculiar. You could tell the movie meant for their to be a bigger reveal of a large ring of men that were involved with this (I suspected the head architect guy and his wife) but it went nowhere. Then leaving it unknown about Rosario.
Seems like maybe the studio didn't let them film it 100% and in the editing room they just put together what they could.
Or just an odd director.
