So I just beat it...honestly, I liked the ending. It wasn't spectacular, but rarely is an ending. It was very good for me as a finale of my Shepard's journey though.
Tengo, tell me what you didn't like about the ending in spoilers and while you're doing that I'll try to think of what I did like about it. Others, I'm curious what you think. JHen, I get your point to a degree, but just because I don't think that there was outright denouement, I think it ended well enough.
