I know ID questions are not good questions to ask but for the life of I can't remember the name of this TV series.
I saw it on either Hulu or Netflix (but don't see it in any of my queues), earlier this year or late last year. It was a newer series, probably last 2-3 years, and it was only one season that I was able to watch. It may have been on one of the major networks like ABC or Fox, or one of the cable networks like AMC or TNT or something. I can't be for sure because I don't subscribe to cable.
It involved a town where only the kids and adults up to age 21 were alive. Something happened when they turned 21, some kind of conspiracy might have been involved. 2 factions break out, one involving the well off kids taking charge of town and a group of outcasts from the wrong side of town. I think the town may have been quarantined.
Really curious to remember, I want to know if there is/was a season 2 or not.
