Friday the 13th : Why did the sequels ever return back to the real camp and town

It had that signature looked that sequel never re-captured, maybe Part 2.

Shaken, not stirred

That's a good question. I'm not sure why they never returned to the original camp. If I were making a sequel, one of my first inquiries would be whether we could secure the rights to film in the original locations. Heck, I'd love to see a new scene shot in front of the Moravian cemetery where Enos lets Annie out. Last I checked on Google Maps, it was still there.

I used to see quite of comments about how the woods in Part 2 do not look like the woods in Part 1, but not so much anymore.
