Synthesis is still bat shit insanity and the exposition only serves to make it creepy. A new DNA. Sigh, good lord.
Control actually kind of works, despite it being very close to that cartoon (which is funny). He is 'The Shepard' after all, now literally. Goes well with the whole messianistic theme. He's basically a god now. Including worrying undertones.
Destroy works, too, I suppose, but I still think Shep waking up among rubble is daft fan-service. But that's Bioware, I guess.
The 'hidden' ending is actually really nice, I think. Good on them for remembering Liara's beacon. That's another one of those missed opportunities that was just bizarre in its absence.
The relays aren't entirely destroyed, just damaged. The fleet leaves before the crucible does its thing, good. Why the Normandy is leaving is fittingly explained as well, which makes me wonder why they couldn't have done this the first time around.
It's definitely improved, but the most glaring mistake, aka everything about Space Kid and the Reapers' purpose is still intact and dumb as ever, but I didn't expect them to just cut with Anderson and Shep dying next to each other.
Also: Baby Krogan. Aaaw. ^_^
Don't they have hundreds of children...? I guess they love each. And. Every. One.
