The main trouble was they had this five year plan all thought out in advance, so that people couldn't just say, they were making it up as they went along, the studios liked the five year plan so much they actually fought each other to be the one to make the show.
Unfortunately it seems like all the good stuff would have happened in the last four years, based on the evidence of the first, plus hiring actors with either no charisma, or for some reason telling them to tone it down if they initially had some, didnt really help the audience warm to anyone on the show.
It took till the mid season break for most of us to even remember the character names.
Being internet geeks we all kept watching just so we could complain about it every week, most regular Joes bailed rapidly after the pilot, thus ensuring when it came time to renewal, that five year plan didn't mean shit, because it got cancelled after the first.
