I still can't forgive planet scanning and the end quest in ME2. I found it worse then any iteration of ME3 to be honest. For as bad as the child was, the final boss of ME2 doesn't fit in anywhere in the ME universe, before or after. It was so bad I could not bring myself to replay that game, just knowing that what was waiting for me.
I couldn't disagree more. The planet scanning is stupid but you can edit your save game file and basically skip it. The end boss of ME2 isn't nearly as incongruent with the tone of the series as the Star Brat is. Not even close.
