I'm disappointed the elcors; the floaty, tentacled pink latex aliens; and the Citadel's shrimp didn't get a lot more face time. I love them and each of those races gets but one character in the game. Especially the pink latex aliens should have at least gotten more face-(well, body-)time, considering how intertwined they are with Prothean/Reaper lore.
The amount of Autodialoge in conversations is a huge problem, I didn't see anything wrong with ME1's system and ME2's was fine as well with Autodialoge added in during times that it made sense. ME3 90-95% of the conversations is autodialoge with maybe one or two choices within the whole sequence.
This does bother me. A lot of the time I feel like I'm watching a movie and not playing a game, even more so than I did with ME1 or ME2.
incredibly cheesy (The Cheesy word should give you a hint as to who I'm talking about).
You'll have to be a lot more specific.

The Plot's ok although I'm not happy about some parts of it being changed inbetween ME2-ME3. It was originally suppose to be about Dark Energy, which got mentioned a lot in ME2.
They hand-wave the focus on dark energy/matter in ME2 away with it somehow having something to do with
Eh... Me? I'm not happy with how they keep redefining what the story is about throughout the series. Red herrings are lame. And deus ex endings are even lamer. It's a shame that you spend the whole game building up this giant army and then, from what I know, you don't even get to really experience the significance of this. I'm only about a third of the way through the game (going by my readiness score), so I'll see what I think of the ending when I get to it...
So far I'd rate it a 9.5/10 although that's basing it as a game overall and not as an RPG, basing it as an RPG, it gets a 3.5/10.
I'd give it about a 7 as a game. They remove your agency too much; the combat's clunky; the dialogue and characters are all over the place.
I'm enjoying ME3 for what it is, though.
Pretty sure the actress is either Aussie or Kiwi. She's certainly never sounded American or English to me at all...
Also, Leydenne is indeed correct. Yvonne Strahovski is indeed Aussie despite the name. She actually has a really strong Australian accent in my opinion, not even close to English.
That makes sense. I was wondering why she sometimes "slipped up" on her "English" accent.

My mind's still insisting she was American for ME2... She does really weird stuff with her voice. I don't know if it's on purpose but she sounds... strange. At one point I even thought she might be Welsh.
