Being the most pure mystery of the bunch, Nancy Drew and the Hidden Staircase is arguably the most enjoyable entry of the four-film franchise, even if the leads’ antics are entirely rote by now. The important thing is, they still amuse, and go out on a high note. It’s kind of a shame there weren’t more.
In this adventure, two sister spinsters announce plans to donate their estate to a children’s hospital. The catch is their father once upon a time designated they must live in it every night for 20 consecutive years, and now, they have roughly two weeks to go. When their chauffeur turns up dead, it’s obvious to us someone’s trying to scare them away by murdering the man and, thus, foil the old maids’ good intentions.
To the loony, incompetent authorities, however, led by Capt. Tweedy (Frank Orth, The Lost Weekend), it’s a long jump to a conclusion of suicide. Luckily, Nancy (Bonita Granville) and platonic pal Ted (Frankie Thomas, whose lower register suggests dropped testicles post-Nancy Drew … Trouble Shooter) appear on the crime scene to fiddle with pieces of evidence and plant a false one. Oh, kids!
When Nancy learns the twist — the one we get from the start because, oh, y’know, it’s in the title — she exclaims, “Boy, isn’t this a pancake!” And that sums up the clean-behind-the-ears appeal of this picture, strengthened by anachronistic plot devices as ice delivery and telegrams. At an hour long, Staircase is hardly taxing. To borrow another two dated exclamations that could sub as a review, “Swell!” and “Hot diggity!” —Rod Lott
Remember when Eddie Murphy used to be funny and he did that routine about how Hollywood doesn’t make horror movies with black people because they’d leave a haunted house at the first sign of suspicious goings-on? Well, now that Murphy is no longer funny, they made that movie. And he must no longer be black, either, because he goes in and stays in that haunted house.
Skeletons come alive, apparitions appear everywhere, Jennifer Tilly’s disembodied head resides in a crystal ball, and yet nothing of significance happens in the entire hour and a half. Nothing but ass-numbing, migraine-inducing pain. This one makes any of the nonsensical 
It’s impossible to watch 
With roughly 14 minutes, no sound and the barest of film technology, Georges Méliès sure did pack a ton of stuff into
