in my case it's not that it is depressing ending, but that it is full of loopholes, plotholes, wtf moments and damn it is not dependant on anything you did through out all of the three games, since the rest of the game was so god damn perfect and the ending was so absurd, i didn't get depressed i am fine with Shepard dying, i was disappointed that a story with such deep thought was concluded in such a pathetic and cheap way... Bioware did promise the "epic" conclusion which we would never "forget", and not that ending is bad that Shep dies or mass relays are destroyed, but it's bad that it doesn't depend on your actions, it was another deus ex all over, epic conclusion was a pathetic choosing of color you want to see in a cutscene... also it stole all the replay value from the game, endings are all the same. also i found rediculous to listening to the star-child writing was just insanely bad, it seems that the ending was written by a toilet cleaner, it was going something along the lines "we created the synthetics to wipe organics out because organics will create synthetics which will wipe out organics, here's your explanations, you can't argue with this logic, now go pick a color and destroy everything"
