The show is about transhumanism.
It's really unfair to judge a show before it's through but I'll play along.
This show is "foreshadowing of the week"
Good storytelling has a lot of foreshadowing and mystery and this is absolutely jam packed with it. What people are complaining about as "lack of exposition" is all foreshadowing.
One of Hiro's driving forces is "why don't the other kids question things like I do?" which is why he connects with 02, who is fighting the whole system.
The kids have a damn color scheme for how individualistic they are. The lower number parasites drop mysteriously out of the government testing program, never to be seen again.
Once the penny drops and the whole thing is laid bare against the transhumanism backdrop it will make a lot more sense, and then slow people will be clicking on youtube videos and rewatching parts of it for a long time.
We haven't even got started on all the weird Norse "coincidences"
If it were monster of the week, or sappy teen drama or this or that shallow thing there wouldn't be pages of threads trying to figure how all this shit adds up. These people are not skipping details, they're purposely muddying the waters to distract you from big reveals for dramatic impact later.
Occasionally, I have seen stories like this fail to just too many ideas that don't fit together that well in the end such as Philip Jose Farmer Riverworld stuff or Twin Peaks but they were still a hell of a ride and they surely didn't lack depth. This is one of those shows but I think they have a pretty neat solution for most of it that won't be disappointing.
In any event, it's very far from the shallow and insipid characterizations people are trying to give it.
