The movie pushes the Windows idiom of modern cinema about as far as it will go, its narrative cleverness offset by the visual tedium of following a mouse arrow around for an hour and a half.

Dark Web: Unfriended needs less reliance on lewd jokes and more on its screenwriting.

Figuratively speaking, Unfriended 2 puts a sheet over its head and says "whooo; the internet is scary". It is seldom as scary as a sheet.

If continuity errors bother you tremendously, there will be plenty of spots in Unfriended: Dark Web that will niggle you. My suggestion would be to go in, suspend your disbelief, and have a good time.
