25. They originally wanted to use practical effects

Practical effects are when special “tricks” are employed to make something actually happen instead of doing it on a computer. Merriam-Webster also adds that, “Films released in the ’70s and ’80s used special effects as proud badges of cutting-edge cinema, but by the mid-90s audiences began to take notice of too much CGI, which can look unreal and cartoonish on high-def screens.”

Since we now live in the age where we can make bring actors back to life by digital recreation and de-age people by a few decades, Stranger Things attempted to return to the use of practical effects. Unfortunately, it took too long.

"The funny thing is that the original goal was to do entirely practical effects. But what we realized—and it really made us admire those guys who did The Thing and Alien and whatever—is that doing practical is really hard. It takes a lot of time and preparation. We were turning out scripts as quickly as we could but they don’t have six months to prep this stuff. You show up on set and stuff that seemed like it would be a great idea to do in that old school way, we didn’t have time to do. It takes a lot of trial and error, so that was a lesson learned. — Ross Duffer"

And when the practical effects didn’t work out, obviously, they needed to switch things up and move to CGI. Or at least, find a good balance of the two. For example, they did really build that monster head.
