When they talked about injecting more humor into ME3, I was skeptical. But this works.
Well, I played through it all, and it was amazing. To say the Shadow Broker's identity surprised me, would be an understatement. It's not hard to guess what they were trying to do when you first step into the room, but I actually found it worked.
It was actually nice having Liara back, too. Her personality got badly mangled in ME2, so I was glad to see that toned down somewhat, made into a more mature version of her own self, instead of a cold-hearted killer. At least that was my experience.
The locations were fantastic, like I already mentioned, and the same is true of the humor.
I don't know what else to say. If this is any indication of the quality we can expect from ME3, then ... well, actually, it'll be a disaster, because how is anything ever going to top that?
There's so much in the dossiers of the squad members I could mention, but there's one thing I really didn't expect: Grunt reading Hemingway. Or listening to audio books. Whatever. I like the guy.
