I'm saving my judgement until i actually see the show. One bad review doesn't mean anything. its the ratings that count. let's face it OTH was never a critics fave and it lasted 9 seasons. I never go by critics reviews anyway, as it all down to personal preference.So if you liked the premise, don't write it off until you've watched it.
Regarding, how it will work out as series, I don't know. It might be bit like The Killing and you might not find out what really happens until the end of season 2.
Anyway, I'm really looking forward to watching it. i like the premise and it's got a good cast plus NBC does tend to get good shows.
