I don't get your point.reapers were not one of main part of plot, there is no need to debate over them. the funny thing is one of you guessed their role exactly. mass effect isn't a game you fight against unknown space invaders, if one focus on this part, he/she will not understand whats going on. no sci-fi cares characters or events, sci-fis are built upon ideas and purposes.
people treated mass effect like a space opera (star wars) but actually it is a sci-fi (kinda blade runner like). that's the reason i am disappointed, i realized people think space operas are sci-fis.
Mass effect was always some kind of space opera. Though this is a fancy word.
At least lots of the marketing was about that and that it is like an interactive movie. And that was actually always one of its strength. At least in my view.
