6.3/10
Senior Film Conservator

A definitive 6.3/10 rating for a film that redefined the boundaries of cult cinema. The Plot Thickens remains a cornerstone of transgressive art.
Honestly, it depends on how much you like watching Zasu Pitts flutter about. If you’re a fan of those breezy, low-stakes mysteries from the 30s, you’ll have a good time. If you want a film that changes your life or keeps you guessing until the very last frame, you’re gonna be bored stiff.
The whole thing feels like a stage play that someone accidentally filmed. It’s got that stuffy, indoor energy where everyone is just walking into rooms, saying a few lines, and then walking back out. Sometimes they move a prop just to prove they’re busy.
There’s a moment near the middle where a character leans against a display case and it wobbles so hard I thought it was gonna tip over. Nobody reacted. They just kept talking about the silver cup. Classic.
If you’ve seen The Triumph of Sherlock Holmes, you’ll notice this doesn’t have that same gravity. It’s not trying to be smart. It’s just trying to be finished by dinner time.
Also, the lighting in the hallway scenes is super flat. It looks like they forgot to turn on half the lamps. Maybe it adds to the mystery? Probably not.
I found myself wondering if they ever actually found that cup or if they just forgot about it to go get coffee. It’s that kind of movie. You stop caring about the plot and start caring about which actor is sweating the most. Spoiler: it’s the guy in the tweed suit.
It’s not bad, though. It’s just… there. Like a coaster on a table you’ve already cleared. Watch it if you’re folding laundry or something.
