The way in which the Reaper's purpose however, was botched. The logic was at the very least questionable, and it undermined the story's Lovecraftian roots.

Stopping the Reapers (resolving the conflict) is the only good thing the ending managed to do (which is one of the biggest reasons the Indoctrination Theory is such a terrible idea). However, they manner in which you stop them leaves something to be desired. The differences shown in the three endings are insignificant, and the amount of similar footage in the three original cutscenes is disturbingly similar.

All that aside, I'd say the ending doesn't have much going for it. It certainly has more flaws than redeeming qualities.
