Been watching the new Netflix documentary series on Spring-heeled Jack and I've got to say, it's actually really good. Not the sensationalist rubbish you'd expect from Netflix.
Why it works: The production team actually interviewed serious historians and researchers rather than just booking randos who claim to be psychics. They visit the actual locations in London where sightings occurred, and they're honest about what we do and don't know. The episode about the 1837-1838 hysteria particularly is well-researched.
The good bits: They lay out the timeline properly, show how mass hysteria can work, and discuss the possibility that multiple different incidents got lumped into one legend. The 'Pogo stick springs as 1800s urban legend' theory is genuinely interesting.
The weak bits: Episodes 4 and 5 get a bit too 'spooky music and speculation' for my taste. They basically run out of actual evidence and start inventing theories. Also, their insistence that it had to be someone's publicity stunt gets a bit thin.
Overall: Honestly worth a watch. Not going to convince you either way, but it's thoughtful paranormal documentary work. Rare enough that it deserves credit.
