I just started the first season of Parks and Rec.
Stay strong. The first season (and parts of the second) is not very good, they were still figuring out the tone and rhythm of the show. It gets amazing, though.
I don't live in the States so I'm not sure about the effects of stuff like this, but cancellation (Community) and rushing (Parks) of shows with dedicated fan bases should give them bad publicity.
Well, the thing is, neither of those shows have great ratings. Parks and Rec has always a solid fanbase that delivers an average (though not very good based on its timeslot/lead-in/etc.) rating. Community never had great ratings and they got worse and worse as the seasons went on. Advertisers don't want to pay for a show that is getting bad ratings. And a show that has 2-3 million viewers that is on at the same time as a show that gets 20 million viewers (Big Bang Theory, American Idol or CSI in their hey-day), is deemed as not cost-effective.
Every year that a show continues, it gets more expensive. If cast and crew rates go up, but the ratings stay the same or go down, then the show is a failure. From a business standpoint, it makes more sense to cut their losses, cancel the show, and spend half as much on a new show. Community got lucky and was able to put blatant ads
into their show thanks to Subway (just like Chuck had done previously). They probably would have been cancelled a year or two ago if it wasn't for Subway. Parks and Rec has always done quite well with critics and helped to anchor other shows, even though its ratings weren't spectacular. After so many years on the air without obvious audience growth, Parks and Rec is no longer economical for the network.
Granted, the entire ratings system has been utterly flawed since the advent of DVR, On Demand, and digital streaming. Hell, in a way, the ratings system has been outdated since programmable VCR recording, but for some reason, the networks still worship it.
