Metacritic has its faults, but hey, it's a benchmark.
Here are other comparator games, first by reviewers score and then by users score:

If DAI can do 88, that would count as a 'return to form'.
Anything over 90 would be a wonderful thing.
The User Reviews are a whole other matter.
A section of the gamer community seem hell bent on treating anything from EA as the spawn of Beelzebub.
Similarly, there are some vocal low-lifes that object to fair player gender/romance/orientation choices and consider BioWare a target.
I'm going to expect 10's in the user review section. I also expect to see 0's.
Anything above 7.0 as an average would do.
Why do I care?
After some mistakes and under-funding for DAII I think BioWare deserve a break.
I like the franchise - Dragon Age is my idea of a good time.
I also don't want those who bang on about DA being sh*t and a game that 'makes your gay' to get any satisfaction whatsoever.
(though I also have no doubt that if the reviews are good, those same posters will comment that EA have 'paid off the reviewers' and have 'made the reviewers gay' or some other nonsense)
