Under Suspicion seems OK until the end, that's when they break with a film making (or indeed story telling) tradition and screw with the viewer in order to create a twist.

A twist that you don't see coming, not because there isn't evidence for it, not because it's not obvious, but because of the audiences POV in the film.

While the twist is for this reason unexpected it also loses the audiences trust, they have been lied to and cheated. This also has the effect of making the ending an unhappy one.

Before the ending it's enjoyable enough although we are asked to swallow some rather unlikely things including possibly the closest life and death 'save' in movie history. (not to mention a justice system that seems extremely speedy)

There would also seem to be a plot hole in that an extremely valuable and lucrative piece of evidence (possibly the reason for the crime) is seemingly sacrificed to save someone when no doubt other evidence could have proved effective.

Another hole is Angeline seeing both sides of a building while seeing fine detail far away in the dark.
