ME1 told us everything we needed to know. ME2 did nothing to advance the plot. It was already set up by the first game that the Reapers are coming. Why do we need to be told that for another 30 hours? It's unnecessary. It's the execution of it that stinks.
The collectors being Protheans isn't significant , and it doesn't help us understand anything new about The Reapers. It's never expanded upon , and worse, the Collectors are inefficient at best.
Also , "we"? Are you referring to people that prefer retcons and plotholes? I'm glad to not be a part of that group.
Let me guess...you hated The Empire Strikes Back because it didn't move the plot forward at all towards the Rebellion destroying the Empire, eh?
No. ESB had development. It's sad people actually compare a bad sequel like ME2 to a classic , smh.
