I'll tell you this much: up here in Canada, we typically get polling during election seasons by Ipsos-Reid, a nationally-recognized surveying/consulting firm that is hired by just about everyone to ensure fair and balanced polling. They ask similar questions to the original poll ("How satisfied were you with x?", "Did you feel that x was not up to standard?"). They would kill for a poll that has 100,000 votes. There are so few polls that have a response of that magnitude, outside politics, that it's an anomaly.
100,000 votes of anything, with such a clear majority, shows you a near-universal trend for a question, product or service.
...
Because it's exactly that - one poll. Of the other information I've read about the game over the last few months (judging from responses by people who actually work in the stat industry, and as I mentioned earlier in this post), the consumer confidence for the ME brand has fallen roughly 40% between March and October. Add to that the general trend that one vote represents 10X its value in word-of-mouth/referral, and you start to see where the general discontent of the game comes from. Every anecdotal piece of evidence seen over the last year supports this notion. Gamestop was reporting a record number of returns for the game (and its unit price dropped sharply -in half - soon after release, which is almost unheard of). The DLC sales are, according to those who actually track the XBox and PSN charts, nowhere near what they were for ME1 or ME2. The Mass Effect Trilogy rerelease was a complete dud in terms of sales, despite having a big marketing push. The sales, if we're to take VGChartz as gospel, shows that 3 did better than ME1 but worse than ME2 in lifetime sales to date, which is not good considering EA made a massive marketing push and had the same time spent in development.
