ME3's backlash because of the ending was dumb. Gamers are annoying.
I didn't like the ending.
But yeah I think the over-reaction to the ending was too much. But then I'm a its all about the journey kind of guy instead of overly being fixated on the ending kind of guy. Some of my favorite pieces of entertainment have shit endings.
It's great when an ending caps off an already great experience but a disappointing ending almost never ruins something I enjoyed a great deal.
Like the Sopranos for instance. Or any of the other dozens of examples I could use.
So I get the bitching about the ending. But not in the context of this ending was so bad it ruined my experience with the games and now I'm bitter about it for all eternity.
