Mass Effect 3 Ending Discussion

[Combine 017]

The game itself was great, just the last 10-15 minutes of it went to shit real fast. I really like that indoctrination theory and that it was Shepard fighting against his own mind, but if thats true, why didnt they finish the game? Either way, they screwed up, but I still really enjoyed the game as a whole and look forward to some more DLC.
