“Alien Sniperess” (*1/2 out of four) was a disposable action thriller about a female sniper (Olivia Okoro) who tries to fulfill the wish of her deceased fiance by leaving her sharpshooting life behind her but is called back into action when a hostile alien invasion threatens to overtake the planet. The direct-to-DVD equivalent of junk food, as it moves relatively quick and is easy to watch, but has no nutritional content and is utterly forgettable. Roger Corman used to produce movies like this in his sleep years ago.
