aka Tower of Terror, aka Sorority House Massacre 3
How bad is it? Technically sub-par, with a hackneyed plot.
Should you see it? Yes. It's one of the best films of its (admittedly cheesy) kind.
Sometimes, early in his career, Jim Wynorski made entertaining schlock like this, rather than the dull drivel of late. This retells Sorority House Massacre 2 (which was no relation to the original) in an almost shot-for-shot remake, with many of the same actresses playing each others' roles from that film, despite having been killed off in it. The title tie-in to Die Hard is due to this film being done in a high-rise, rather than sorority house. Five girls doing inventory open a box containing the spirit of a killer, which then goes on to attack them while they show their breasts for implausible reasons. The effects are outlandish and silly. Forrest J. Ackerman makes an appearance. It's dopey and mildly offensive to women or anyone with taste, but it's a fun watch.
