I actually really loved this game, but wasn't really
"surprised" since I had high expectations to begin with XD
The only campaign I was actually pleasantly surprised with was Chris' campaign, because it's the only campaign I didn't have high expectations for. I thought it was just going to be huge testosterone action, with less story and character focus, but I was wrong! It turned out to have a great story (like all the campaigns) and it was way more emotional than I expected.
Also, Ada's campaign was amazing! It felt the most like old-school RE with the puzzles and single-player.
And, in response to this...
I hate that Capcom has taken away backtracking large areas, but hopefully they will bring it back.
What about Revelations? That game had plenty of backtracking since the majority of the story took place on the same ship. And that came out fairly recently. Revelations gave me a lot faith that things
can go back to the way they were, while still incorporating elements of the new games
