Timecrimes

★★½☆ – (2007) – A man inadvertently travels back in time to avoid a killer, and gradually learns the dark ramifications of repeating the past. Has a unique premise that takes plenty of unexpected turns, although some events can feel muddled. Has moments that question logic, but is moderately gripping overall.

47 Meters Down

★½☆☆ – (2017) – Two friends become stranded in an underwater cage beneath shark infested waters. Does manage a moment or two of suspense, and the overall dread is fitting, but the rancid dialog all but destroys the experience. The characters are annoying to the point where one can’t help but root for the sharks.
