TRR: This year marks the 25th anniversary of Home Alone — and what better way to celebrate than with a terrifyingly tense foray into the home invasion sub-genre? Set entirely within the confines of one domestic dwelling, Shut In centers on an agoraphobic young woman named Anna (Beth Riesgraf) who's forced to defend herself when three intruders (Martin Starr, Jack Kesy and Joshua Mikel) break in one day in search of ready cash. Instead, what they find is a house full of shocking secrets and its surprisingly strong-willed occupant, a would-be victim who turns the tables on them in the most unexpected way possible. Curiously enough, the movie has been retitled Intruders for its wide release. However, the original title is infinitely more fitting. After all, the central focus of the movie is Anna, and Riesgraf delivers a compelling and forceful performance in the lead role, painting a portrait of someone who is both fragile and courageous — both a victim and an aggressor. Anna isn't your typical horror movie heroine, not by a long shot. By that same token, Shut In isn't your typical horror movie. It's a siege thriller with a twist — a tale of survival with a mean streak and an emotional undercurrent so raw that it makes the terror on-screen feel all the more real.
