What seperates a user score from a real review is that a userscore is typically emotionaly based.
A real review takes in sound, voice acting, textures, polygon models, pacing, action sequences, enemy AI, shooting mechanics, dialogue choices, side missions, replayability, and overall plot.
The ending would only hurt the plot score, but not by much since it doesnt hurt the plot during the rest of the game. Replayability could also suffer due to the ending being similar in nature.
But even then your looking at a game in the low 90's because your SUPPOSED to review everything (see above checklist). To say the ending negates all the hard work Bioware put into the game only further proves to me that user scores shouldnt exist unless they are purely objective
