I didn't hate the ending either, but I will grant you I only ever saw the Extended Cut. I did dislike the final mission - it was brutally difficult to the point where I said, "This isn't fun any more".
I'm more than willing to give Mass Effect 4 a go. I'm in it for the story, not the game mechanics. I'm interested to see where they'll take the story since they now have the opportunity to take it in any direction.
