All in all, okay. The little glimpses of the different characters and societies rebuilding were pretty much exactly what I was hoping for.
Synthesis still seems like a magical perfect utopia with no explanation, but whatever. Clearly BioWare thinks the whole Synthesis idea is just
so awesome man.
I actually kinda liked Control a bit more than before, I still feel like it conflicts thematically with pretty much the entire series up to that point (the Illusive Man... was right all along?
Uh, NO), but I liked that AI-Shepard seemed to have this little edge of menace and otherness to it. I didn't feel like he was totally benevolent and that everything was automatically going to be okay. It was a little unsettling. That was good.
Refusal... yikes. It was good in itself, but seems like a big slap in the face to fans from the writers. "Don't want to play by the Catalyst's rules? Fine, now you have the option... AND YOU LOSE." This is not going to make people happy.
I'm still hoping that the Destroy/Shepard survives ending has some kind of extra hint toward a reunion with the squad and LI. But I don't have my hopes up too high.
And one major change I noticed. The green and blue signals no longer damage the Normandy. That's not a "clarification," that's a straight-up retcon. Either the Normandy's engines exploded or they didn't.

It also serves to make the "Eden" scene make a little
less sense now, if that was possible. So the beam didn't blow up the Normandy, but they still traveled to and landed on a mystery planet in another system... just because?
