I loved seeing it - it was like a cross between DS9 and TNG, it allowed explorations all over the Earth but yet still centered on the Earth (except when it left that behind and went to the stars:-).
It also tells a story of skepticism b/c these angelic, gender-neutral beings descend from the stars and yet… not all as is people might wish for it to be. It kinda went DEEP into exploring some of those concepts that were harder to do in the Star Trek universe - b/c the Federation was just so culturally evolved, it being in the future, while EFC was essentially the present, heck it’s likely the past even by now, if alien technology were just suddenly handed to people.
One thing that really intrigued me was the focus on more biotech than physical tech, and also the updated technology to show special effects allowing the aliens to be literally beings made of energy (these ofc existed even back in TOS but… it’s nowhere near the same), which put on a fleshy shell most of the time for convenience but often reverted to show off the cool special effects for uh… “reasons”. And since you see these beings day-in and day-out, not once in an episode and then gone, you really get to explore how such a thing would influence their thought processes, like did their ancestors hunt for food or like… what? (btw you not knowing next to anything about them is very much a part of the experience of watching the show, so I will not spoil it here:-P) DS9 did a lot of that with the shapeshifters and a little bit with their genetically-modified servants, but in EFC Gene Roddenberry did it differently, with these energy(plasma?) beings.
Anyway, I hope you enjoy at least checking it out!:-)
