Triangle ★★★★

My knee-jerk reaction is to give this a favorable rating. Will revisit my rating after subjecting it to sufficient scrutiny. The central theme makes it compelling to me. The execution is so-so. Tone, character, plot, casting, acting, and dependence on distracting CG  are all pretty perfunctory.  I still recommend it though. It is daring in its own way, and adds something to the contributions already made by similar films like Stay, Identity and in some ways (one particular way) even Hereditary and Netflix's miniseries adaptation of The Haunting of Hill House.
