I always feel like ME2 gets off very lightly for doing essentially nothing to progress the main story. It feels like the story could have been used in a spinoff game.
Part of ME3's problem was that it was left with too much to do, the Reaper invasion needs to be started and concluded in the same game when it should have been started in ME2.
