I see. Not familiar with who wrote the ending or what they even look like, I just saw a dude with his head turned toward a monitor.
That being said, I want to have faith in this, but I had a lot of problems with the game, and not just the ending. It wasn't even necessarily the ending but rather the entire third act lacking any oomph or great storytelling moments. It didn't feel like it ever reached a climax and there was no identifiable villain standing in your way. The story had no Emperor Palpatine or Lord Voldemort. The Illusive Man just showed up here and there with incessant blabber so he hardly qualifies.
Not saying everything needs one singular villain, and the Reapers are threatening villains, but hell it needed something.
